- I have a new favourite development board, this board is made by LilyGO, this is T-display S3 AMOLED. Yes , for the first time we have AMOLED screen on the development board. And it looks amazing. Colors are beautiful, black is really black and everything looks sharp ,modern and simply beautiful.
I am using the Arduino IDE and tft_espi library to program it. Feel free to use my examples. I hope you will learn a few tricks. Many thanks to Nick, he edited driver files and made this possible.
You can buy T-Display S3 AMOLED here:

Mine has arrived and I love it! Thanks so much for sharing this information and your incredibly useful example code.
I noticed that the image header format is slightly different in the image scroll demo but I got an image to scroll nicely eventually.
The Test example would not run at first but after a quick bit of research I updated my TFT_eSPI library to version 2.50 in Arduino and it's working great now.
As near as I can tell, this display is maybe 350 nits. How do you think it would work in bright sunlight? I was considering transflectives, but there's few options at the size I need. This is a little small for my neeeds, but the resolution is good.
Thanks for keeping us on the leading edge of the ESP32-S3.
Your ESP32 videos are most delightful. Now I want more boards too! This is the way.
That is a sweet display board. I can't wait to give it a shot. Thanks for sharing it
I don't think my first android phone had a resolution bigger than this.
my was 480, i think :)
@@VolosProjectsEven with the Screen, does this esp32 still come with WiFi and Bluetooth Module? Just curious.
Question for you my friend, what is the voltage of the small battery pack used to power your projects
Whatever HTC G1 had
Nice display. I really like your updates on maker-friendly displays.
Very beautiful!
Just ordered. Thank you!!
Keep up the great work!!
THANK YOU SO MUCH FOR MAKING THIS VIDEO
What a great little board!!!! Thanks!
Great video, thanks Volos.
Your English is good and I understood your explanation of Hello World. Keep up the good work!
I clicked on this video so fast! The display looks real nice and will give people more flexibility in their designs with all that extra screen resolution. Your demos are also improving greatly too. LilyGo do a great job on their hardware, but in my opinion as a seasoned developer their software is lacking clarity and variety, which is so bad when potentially thousands of people will be interested in developing on these boards.
i totaly agree. Thank you for comment.
I think they've got their work cut out. They seem to be releasing more boards and with greater variety than any other manufacturer. Long may that last but you're absolutely right. Software support is more than half of the product - especially in this space.
@@VolosProjects What model is the actual display? I already have an S3. Thanks in advance for answering.
Okay, you sold me on it. Just ordered mine and can't wait to try some of your projects with it.
Thanks, bro. It was very helpful for me.
this is the starter...my project..thanks alot broo
You always make sense to many of us. I've used many of your examples and found them to be spot on. I still have troubles but I am learning.
I am struggling to make a computer interface from a fancy fuel injected CAN-BUS drivetrain so I can install it in a 2002 Tahoe vehicle. To make it easier I use a MEGA2560 for A/D sensor inputs, switches and PWM motor controllers and MOSFET outputs. I keep this separate as I am not an experienced programmer. Then I am using I2C to the LILYGO T-Display-S3 for display. This avoids an excessive interrupts and library conflicts; I hope.
I see your link is out of stock so will check back later.
Soon I will add an RP2040 with dual CAN-BUS and hope I can translate between the computers messages.
Things are progressing well - Thank You for the help
interesting project and nice aproach. i think there ill not be problems comnicating with rp2040.
This sounds like an awesome project! I just glanced at your channel and saw a few videos. I’m gonna check it out and I’m hoping to see that projects process.
Amazing work! Thanks for sharing.
Thank you too!
Hi Volos, Great projects! However I am stuck when I try to modify the ImageScroll sketch you made. It always ends up looking not good. I am sure I am putting in all the right variables tho... Could you maybe make a video explaining how to draw just a picture to the screen of the Lilygo T-display-S3 AMOLED? It would be of great help!
Hi volos , great video ! inspired me to order my own board!
I ran you examples and they worked great , however the main demo you have running at the beginning of your video shows an fps >30 , I am getting about 25 , Do I need to update the driver or something ?
thanks in advance !
Very thorough video... Love the fact I can find board setting for Arduino IDE as I have a lot of different boards (this can save a lot of time), only wish all projects included "board setting" at comments in code...
looking forward to learning more about this board. I'm also interested to know which one of these boards might be bright enough to use in sunlight. For example, i have some projects for use inside a car and some displays are just not bright enough to see during the daytime.
Nice video, well done, thanks for sharing it with us :)
Thank you for showing the new screen sir! You’re making me spend a lot of money. I now have the TTGO T-Display, T-Display S3, both T-QT’s and the T-HMI.
Looks like I’ll be buying this also.
For LVGL you need the LVGL folder in your Arduino libraries and you need the LV.config to be outside the LVGL folder.
If you are using square it is just easier to change the preferences from Arduino\libraries to the specified folder but in that case all you need to do is copy the LVGL folder over to the libraries folder and take the LV.config file and place it outside the LVGL folder.
Let me know and I’ll make a private video of how it works. It was a bit of a nightmare for me u til I got it right.
All that aside, I have learned so much from your videos and code that I can never thank you enough. Maybe I can help you with the LVGL thing as I am sure with your experience, you can create amazing UI’s using Squareline.
Take care for now and keep it up! You are helping us more than we can ever show you.
Thank you my friend, i will aceppt your help, maybe it is time to learn lvge ans square line.
@@VolosProjects I’m a real amateur so this is perfect.
I will show you what little I know and then learn from you. It is a win, win for both of us my friend.
I shall be in touch!
@@VolosProjects Hello! I can help you with LVGL and SquareLine if you want, I know how to get it working with all the ESP32 boards in your channel and I’m happy to help
@@VolosProjectsI would second this, I've been using SquareLine for a few months and it's pretty good. It's not perfect, for example a few important LVGL components are missing so you have to add them with code, still it's a great way to prototype UIs and quickly build demo code of how to implement various styles in LVGL. I've also noticed that the UI on device doesn't always match the editor, especially with nested components. I'm not sure what their release cycle is like, it's possible these things will improve over time.
@@VolosProjects I'm thrilled to see the videos explaining it ;)
awesome job !!
Nice video. What is the smallest screen that you work with or know of?
amazing!! thanks!! what software do you use to make the image?
I've seen some similar boards with 4" square lcd displays connected via rgb (not spi) to an esp32s3... all the example videos show awful rolling shutter effects when they update the screen, but you image scrolling examples are rock solid. Is that a feature of the board, or just good code?
Great work
You are awesome!
Can you use the sprite examples you made also with the older Touch T-display that you have in your other videos? Or do you need another driver for that instead of the rm67162.h and .cpp files?
Nice work! Do you have a spec/link for the external battery and connector you are using to power it (instead of usb)?
beautiful ,very nice winter project
Hey! awesome, was waiting for this one :)) Does the new board has a better battery management? I have seen that there is now two Vbus previously N/A. :)
Would expect a frame buffer .draw() refresh to be done via timer interrupt on the 2nd CPU. Hard to imagine adopting a whole new graphic drawing paradigm being necessary for this thing.
It does look really sweet though.
Wow awesome channel!
Do you think you might look over the "WT32-SC01-Plus" board in the near future? It's 3.5" Capacitive Touch ESP32, all in one. The "Plus" version skips IO access for faster frame rate. It seems impressive for $30.
It's the best dev board that I've tried. You can get 60fps on it with simple graphics and LVGL will run between 20-40 fps which is pretty impressive for the resolution. I thought the similarly sized makerfabs display would be better with its 16 bit parallel display but the lack of PSRAM can be pretty limiting. The makerfabs board has much better documentation, though. I ended up referencing random github repos to figure out how to get the WT32's display to work. Biggest downside is the lack of a flash button so if your upload fails it will boot loop and you've got to assign the port just before the code finishes compiling, hoping it happens to be connected the very moment the flash begins. It takes several tries and it's a pain in the ass.
What is the PWM dimming frequency?
wow thats so clear can even make it out wear big prescription glasses
do you know how much voltage this board can be powered by? I don't want to use USB to power the board, and I don't want to use battery power. can I power it through another method?
Hello Volos! I have been watching your videos and they have been incredibly helpful!
I would like to ask you more questions about the best processor and screen or combination of both for my projects, please?
Hello, what you want to know?
I make gauntlets for the cosplay community, and use an ili9341 lcd screen, an esp32 and sd card to play animations, but they are not gifs, so the animations are not fluid. Was hoping to figure out best chip and screen combination to play short animations and not a lot of hardware?
Your english is perfect!
Thank you very much for the nice videos. Please think about for making a project based on esp-idf/FreeRTOS framework instead of Arduino.
I have one of these and clueless how to use it. Thank you
Great video and great sample projects - as always. Thank you. Quick Question - what software did you use to make the spinning head animation and create the C file for include in the source?
Hello, i have my own script i made for this purpose.
QUESTION: is there any significative difference in brightness among the T-display-S3-AMOLED and the T-display-S3 ?
I would like to use it for an outdoor application, for example under direct sunshine.
I plan to add a (very) generous sunshield around the display (top+left+right), the same I wonder what would be the best choice between these two displays.
--------------------------
From the video, the old T-display-S3 seems slightly more bright. It is just my impression?
This display looks great, the difference is clearly noticeable. I'm worried about its lifetime though, AMOLED screens are notorious for burn-in issues and I don't think it would be a good idea to leave it on for long periods of time. It also looks like this version doesn't have touch support, and that it's only an option for the LCD model at this time. Finally I wish the LilyGO boards had at least _some_ sort of mounting elements, even if it was just a few holes. I find that their absence makes it a lot more difficult to design enclosures for projects, unfortunately.
I think libraries should implement auto pixel movements to lower the burn in issues.
tnx desmond, for now we dont know answer to that. i hope it will last.
I've got 2 of these boards now and one has been left on pretty much permanently for about 6 weeks with some bright static elements. I see no burn in (or really 'fatigue' of the blue subpixels). Under normal circumstances I would never do this but as a test the results are encouraging. I added a brightness control to the driver code so dimming all the way down to zero is possible and perhaps useful for 'always on but asleep at 10% brightness'. The default lilygo brightness is set lower than max. I would avoid max (0xFF) as it's ridiculously bright and probably not long term healthy for both the display and your pork pies. The software dimming gets a little shimmery at low brightness as it uses PWM which seems to strobe with display refresh a bit. There is a better approach using DC control but it would require a slight hardware revision by Lilygo.
I'm told that touch models are coming. Lilygo already showed off a amoled version of the Touch-Bar on Twitter.
Yes mounting is a pain. But since amoled has none of the horrid side bleed of backlit TFT which we feel we must mask with bezels etc, I'm delighted to leave the whole board in plain sight in a clear acrylic enclosure. The headers are secure enough and you can use a right angle USB C to panel extender as strain relief.
@@nikthefix8918 that's a good input.and thanks for your work too. my boards should arrive very soon, very grateful for the TFT_eSpi addition :)
@@user-gs5db1it4h Thanks for that. I'm very enthusiastic about these boards as I've wanted esp/amoled for a long time. TFT is great most of the time but for some of those more artistic projects, a cool bedside clock or a faux nixie or flickering candle you don't want the backlight to give the game away. The colours and pixel density are also a massive upgrade. I hope more maker boards start to feature amoled.
can this be used as a computer display?
Thank you! Is it possible to use ESPHome / HomeAssistant with this board?
I've got a LilyGO T-RGB ESP32-S3 with the round touch screen and I've been struggling to get a simple animated GIF player working, do you have a project file or any advice?
I have a cool DIY project in mind and I only have basic knowledge to work with electronics so I was wondering, if would it be possible to use this screen on a battery and to receive data to be shown on the screen, from my PC. I would like to use the screen on my SIM rig, to show me the telemetry data from games using Simhub tool. Any thoughts on this?
Thanks for a great introduction to this board! I've been able to display an animated GIF on this excellent screen. But I appear to be forbidden to post about it here. :) (they've all been deleted!)
hi can you pm how to convert a gif to array?
Can you do a video on setting up the VS Code environment / OpenOCD such that you can debug an ESP32 using Jtag (ex. ESP-PROG or other FT2232HL based jtag adapter)?
I'd like to set breakpoints, step into, etc!
I've purchased a new Lilygo AMOLED, I'm trying to get your examples to run but the text section exceeds the available space on the board. I'm using the most recent version of TFT_eSPI. any help would be appreciated.
I am a huge fan of your work Volos! Your teaching skills are fantastic and you should be proud. I'm having some issues with Transparency and Sprites with the Amoled Screen using TFT_eSPI library using Rick's drivers. Colours work great until I use TFT_BLACK transparency parameter to push them onto another sprite. When I do this, I get inverted colours on the sprite being pushed. TFT_Blue looks red and TFT_Red looks blue etc. Have you had this happen to you? I'm going a bit crazy trying to figure it out 😅
You know, sometimes talking out loud makes you think of the solution. Only minutes after writing this comment I found that the issue was the .setSwapBytes function. I'm not sure exactly how the .setSwapBytes works in nested sprites (ie if some sprites need it swapped and others don't). That may be an idea of a more advanced video 😊
hahah, i am glad you finded solution :) Thank you!
Can you show both the displays side by side in the sunlight?
Its good board for project like mp4 player? Or what u recommend for project like that with good DAC.
Will the same code for the Gifs work on this screen?
Can this unit be made into a rf scanner for high 1ghz to 7ghz?
Or is this asking too much from the unit?
Volos, I really like what you are doing; you inspired me with this project to get one of the LilyGO T-Display S3 Amoled. I followed your instructions. The hello world worked fine, but when I uploaded the image scroll project, it seemed to upload fine, but now I have a Blank screen. The Greenlight works, but I can not see anything. any Idea what the problem is?
You probably did not adjusted board seting in arduino ide properly, flash size or partition scheme. Go to board github rep and ther you can find recomended board seting for this board.
Thanks for the video. I have a project I'd like to make but I suspect that the ESP32 won't be good enough. Well that's why I'm writing this message, with the ability to display 30-50 fps would that mean that it would be possible to have a camera feeding a live image to the screen? I'm talking about a camera connected directly to the board physically not via wifi.
I want to make a viewfinder or digital monocular.
Thanks
exactly same idea here.
This looks fun i really wanna try it out. Does anyone know if there are some practical use cases? I am thinking about using this for some kind of Dashboard in home assistant. Does anyone know if that could work?
When does the touch version come out?
Hello Volos. Which architecture are you using in your firmware ?
Can you describe us the way that you form those projects ? Is there any template ? like a state machine or task scheduling like RTOS etc.
Please do a video explaining DMA on ESP32-S3.
how do i get this screen with a working board WITH Lorawan for Meshtastic compatability?
Amazing Video, so much so I went and bought one, but then Ive realised my lack of skills is now a major issue, does anyone have a link to how to get setup Arduino IDE on a MAC configured to program the OLED screen up?
is there way to use otg with tdisplay s3?? I want to add keyboard
Can u flash a mp4 on loop. Looking for a display for a 1:6 diarama. That screen would be perfect
I found the answer to my problem. I don't know where I read it. Who ever it was thank you. I could not get the new ESP32-S3 Amoled working. Someone had the same problem and downgraded the Arduino IDE from 2 to 1.8.18 and Volos projects run fine. WTF hours and hours of troubleshooting I have a fix and no idea why.
Fantastic work, and your English is great. Where are you from, may I ask?
Thank you, croatia
Hello. When my battery is full charged, the reading in pin 4 with analogRead(4) give me "697". I have a battery 3.7V 300mAh.
Using your code, it print "1.1 vDC" when full charged.
What changes do i have to do in code to print the real voltage (should be 3.7?)
Hi @Volos how can you solder the header pins with the LCD attached? is the LCD removeable? thank you for your reply.
Yes you can, you need to use small tip, and do it slowly
Where exactly do I find the 'nikthefix' guys channel? I can't seem to find it.
cool
Hai mate i am looking front car detect distance between cars, if you have please share
Would you happen to know if it would be hard to remove the acrylic?
I want to embed the whole board and screen into a case and the acrylic would just be in the way.
You can't do so easily. The acrylic frame has a CNC-routed recess in it, and the display panel is held in with double-sided tape. I don't think it's possible to remove the display without cracking it.
You're best off buying a replacement screen. I've done so and it's delicate but not impossible.
This T-display AMOLED would be very difficult to use without your excellent examples. Thank you. Could you please tell us how you created the Image.h file in the Image scroll example?
Ok, I found it was 16 bit colour RRRRRGGGGGGBBBBB 2 bytes per pixel and I could convert a .jpg image using Github FileToCArray. Again, thanks for good content.
Thank you, well done, you found solution.
Thanks for your video. I purchased version 2. I have this problem: If I use the demo sketches made available by lilygo everything works. However, if I use your sketches, the display remains totally black. Do you have any suggestions for me?
Finally got it working. initialize the pins in the right way (i have a revision with same board of touch but with normal display) is the answer to my question.
Can you add this to a flipper zero, just an idea
Fast enough for FPA ?
What are the NC pins used for?
Can I reroute the NC pin to ADC1_CH2?
i think not, they are dead pins, not used and not conected to anything
What is the life of the battery in standby/deepsleep? The product page omits that... Unless it addresses real use cases this is useless, to toy around like that I can use a cellphone.
Can you temporarily remove the graphics screen in order to solder header pins to the bottom of the board?
The display and its acrylic frame are held in place with three pieces of thick gel tape. You'd need to cut those tape pieces through and remove them, then replace them when you'd finished soldering. You'd also need to be really careful since the ZIF socket and the ribbon cable are really fragile.
Or just solder down from the outside of the display, very carefully!
Followed the directions to setup Arduino for the T-Display. Screen booted up and showed the Lilygo startup. After uploading my first sketch, it no longer shows up on my mac under the ports and rst light is blinking red and the green power is up. tried the reset button but nothing
Do you have exacly this board?
@@VolosProjects I have the LilyGo T-Display S3. I got it to finally work. I am using the new IDE and noticed it had espI to install. Removed the one I downloaded. Installed that one and found the line that referenced LilyGo T-Dispaly S3 and its working :)
ok, but this code is not for your board , this is for T-display S3 AMOLED, this code will again make mess in your board.@@davidwalton6308
Τρομερό!
Seems like its not available anymore?
What board should I use with the AMOLED display. Is ' ESP32s3 Dev Module' the right one?
Yes, that is right one
screen looks insane for a gimmick device
Отличное видео, работающие примеры, спасибо!
Is this a LoRa radio?
I hope to learn how to program these in Rust - we'll see
Worst thing of the S3 is that it only has Bluetooth LE, no classic Bluetooth for audio streaming e.g.
Looks cool but what is it useful for?
It is programable development board, if you are building sime devude you can use this to show values , to make ui
I want you to be rich with the 2% support when we buy a board :)
On their site, they have two options: solder and non-solder version.
What is the difference, and which one do you have on your video?
Solder is with header pins soldered, no Solder is without, i have without, same board, if you plan to use this on breadboard take versions with pins soldered. Thank you for helping me become rich 😀😀
@@VolosProjects Thank you for the reply and info.
Production Tip:
Your audio track is filled with "plosives". These are caused when you pronounce words containing letters such as "p" and the sudden expulsion of air strikes your microphone.
The solution is to position a "pop filter" between your mouth and the microphone. Typically, these are very inexpensive. The designs vary from a perforated disk to a piece of fabric stretched over a hoop.
Thank you, i am getting pop filter and New mic, i am awew that audio quality is disaster. Tnx for your help
Sadly no touch version, yet
Can anyone tell me what the power draw is for this board?
It depends, on 10 mhz without wifi it is 40ma, same configuration in light sleep is 17ma, full speed 240mhz and using wifi is 150ma sometimes
@@VolosProjects Thanks! That is very helpful.
