The CH559 is a 8051 architecture based microcontroller that has built in dual USB Hosts. This allows to interface generic Keyboards, Mice, MIDI devices and in my case gamepads. I added this chip as an add on to my ESP32 based game console to replace the SNES controllers by cheap generic ones. The communications is handled over UART which can be done by both ends in hardware. There still is some work to do but you can try it out already. Have fun!

This was a brilliant hack, a fun project, had great editing, and was quite funny! Well done on all counts!
How you soldered everything on that board by hand was great. I love tech and diy projects (even though I can't do 90% of them). You got a new sub.
Well done for breaking through the documentation for that IC! USB hosts are such a useful tool to advanced makers.
Congratulations! That's going to be useful in so many projects.
It was very nice to watch the time laps part. btw props for those soldering skills 👍
Awesome stuff as usual! This chip looks like an awesome find, opens up quite some possibilities.
Is a fantastic project. It really is. You are a very likable guy and your work is done with such a joy and you can tell. Your jokes are also very nicely done. Two thumbs up and you just earned yourself a subscriber. Well done.
Brilliant video Bitluni, amazing work!!
Wish I have such friends who are so enthusiastic about electronics projects. :)
Incredible again. Belated happy new year guys!
Happy new year
Who knows, you might meet someone @ Function '20 :-)
Join a hackerspace?
bitluni, you the man, bro. Awsome update!
I'm always amazed by the hidden gems in the Chinese ICs.
maximum effort chan
great work
3:45 Plugging USB correctly for the first try is illegal!
Insert with the open tabs up, 60% of the time it works every time.
insert with the usb logo on top, works 90% of the time, every time
As written by others, you have between 60%-90% chance of selecting the correct orientation the first time(dependent on how much time you are willing to spend). This means that you can insert it correctly the third time(fifth if unlucky). -not too bad.
video was obviously edited.
If you can SEE the NO-SEE, you got it right UP (or in front) the first time.
What I mean is that there is an indentation in the center of the metallic end you insert into the socket, looking a bit like a nose on a LEGO figure head. The back is a cracked hairline :ø)
Me finding this 2 years later :p Now the Pico W was just released and has a USB host + another USB via PIO. I am going to try and use that for my project, but this is an incredible backup resource. Thanks!
Makers like you are the solid backbone of this community.
i love this man so much. fantastic videos
I don't press the "subscribe" button often or easily, however, I've been following you for a while and your channel is so amazing with such nice, interesting and cool content that I subscribed and I will also become a Patreon member!
Awesome what can be done with today's technology!! :)
great skills man !
Awesome video. happy new year :-)
Great work - thanks for sharing!
Exactly what I was looking for
Every day whit a bitluni video is a good day.
Great job you have done :-)
Thanks for sharing this new way to communicate :-)
Just awesome! I wish I had your skills too :).
Great video and well done.
Bet that was frustratingly fun 🥺😫😅🤔😁🤑
i like the cute little crt you have.
Verry good work. Thank u
This is really useful
das ist mal sehr interessant :)
This guy deserve a medal
Incredible !!!
Great Video. Subscribed
oh this looks like a big promising update that could also(expanding on this) make usb to bluetooth DIY overall better.
crazy good shit as usual
Awesome Video👍
One of the great shortcomings of the ESP32 is it not having a USB interface.
@@BlackTigerHD I wasn't talking about a programming interface which is usually a only a cheap USB-to-UART chip, but about a real, native USB interface, like it's common with Atmel chips, like the 32U4 or SAM D21.
@@yazdanvakili7057 Sadly, ESP32-S2 will sacrifice a lot of other functions, like no BLE, no Ethernet, no SDMMC.
@Z80 None of them have the massive feature set of the ESP32, though. At least not at that price point.
Let's wait for a ESP64 to rule them all. Amen.
@Z80 I can name one STM32F411 project on youtube: betaflight ;)
man, your soldering skills are beyond this realm. LOL .
Aswome project!
Great Job!
FTDI makes a number of these types of chips, and they are better documented and supported. The FT120 looks like similar style, using a parallel interface instead of uart.
nothing from ftdi costs $1 and it's funnier to get something like this to work than a ready-made meal.
You are just one of the kind! I wish I know 10% of what you know! I can'r even come close to your ankles, but I do enjoy your videos!!! Thank you very much and keep up the good work! Wishing you, your family and friends a great happy and prosperous 2020! What do you put into your water to sonic-clean your boards? Thanks.
Awesome!
This is the first video of yours I've watched. Loved it!

And there it is, the pre-stream video release to announce the makercast stream!
FTDI also have USB Host chips like these called "Vinculum". They also have a ready to use UART firmware. 😁
u got my subs
Verry nice!
Impressive!
Useful!
Avr maybe be expensive, but you get awesome documentation.
Thats why i stick with pic or atmel.
This is the first video on YT I've watched that hasn't made me shake my head when seeing someone using soldering tools :))
But why for the love of jeebus, would you want to replace the SNES pads? They are gamepad perfection! And for a crappy USB clone SNES pad. Are you crazy?! :P
I use the ATMega8U2 MCU as a USB host/client on projects. It's under £2, and has a lot of good documentation and examples for all types of usage. It would be good to find a chip that justs passes the USB peripheral data across to UART without needing to be programmed though - to save a step in manufacturing! A bit like the CH340 does for USBSerial
thank you
Some serious soldering skills. I would never be able to do that...
I'm sure that you would be able to do that! He used additional flux on pre-tinned pads, this makes it very easy. Most bad soldering experiences come from bad circuit boards with corroded pads and components with corroded leads and not enough flux to clean it up.
The SAMD21 is an ARM unit that supports USB host mode, according to it's datasheet.
You kick ass.
You should make one with vga so you can just stick it on the back on an old monitor , very small and tucked out of the way. This would allow for a smaller enclosure and it would be cool to see a esp based gaming platform on a dongle . Most CRT were VGA or DVI .. I like this tiny TV you show at the end of the video I have so many things I could use it for.
1:44 - oh how many times I have seen that before! :D
Thats a great video, I think PIC18 or PIC24 have USB too but might be a bit more expensive they have better software though
Klasse!!!
Very nice. As usual, you videos are quite informative. Now a quick question. Can the device function as a USB host for MIDI? Can I plug my music keyboard with the modern USB midi and can I channel it to somewhere else(say a 5 pin midi)
Also would these boards support USB hubs(powered/unpowered)?
Thank you for building great content
Huh. I've been trying to work out the logistics of adding USB host support to devices for a while now.
I have about a half dozen projects that could really benefit from this...
Many of which have to do with retro computers. (for instance - I wanted to add 3.5 inch floppy support to an 8 bit atari. There's many ways to go about this, but one of the most accessible that doesn't rely on obsolete parts, is to use a USB floppy drive... Which... Means being able to build a USB host controller and interface it to the IO connectors the atari has available.)
Then there was a SNES cartridge designed for homebrew development work and software testing where it would be useful to be able to do remote debugging with a PC, but where it would also be useful to have a way of attaching a USB keyboard...
(I'm also currently looking at something equivalent for SATA; mainly so I can interface a modern DVD drive to a very old computer. But my guess is that's even more complicated than a USB host...)
Soooo close to what I'm looking for. I REALLY want to be able to build a USB Host bridge so that I can turn a keyboard into a wireless keyboard (without "stealing" the firmware from a more expensive USB Host). So I need a USB host and some sort of wireless communication to some other unit that can be a USB slave (teensy or arduino should do).
Please implement a USB-MIDI Host to serial driver! Pretty pleeeze!
yesss i need that
Perfect sound, what mic are you using?
Now, you can also take a C3/C6/S2/S3 series ESP32 witch all have USB support integrated ! :)
This will be awesome if was portable version, maybe a PCB that can have even the controller on. The low power required by the ESP 32 to run and the low resolution that will be just fine for a screen with 800x480 resolution.
Wow its just amazing... I like this project!
Can you add insert coin for playing a game just like an arcade?
Good
Since even broken Amiga 2000 keyboards are going for $240+ on fleabay, this little chip might be just what the doctor ordered to adapt modern keyboards and mice to work on amigas!
Also if you don't need USB Host and a large program memory, you can try CH552/CH554 which only comes with USB Device mode. They are really cheap and I have already tried to make a small USB keyboard by modifying the provided example code on WCH's website.
I had to go with the ch559 since I want to have keyboard and mouse in future and a usb hub ic costs more than using the 559 in the first place
@@bitluni Yeah, for any use cases that ultilizes USB Host mode and multiple ports, CH559 is a solid choice as it provides double port root hub, while still cost effective. Thanks for sharing!
Nice work. Anyway, instead CH559 a good choice would be the PIC32MM0256 (a little over 1Eur) which have USB OTG and an excellent and free software (MPLAB X) with plenty of samples.
MPLABX isn't free if you want optimizations... you can compile with chipkit also but it doesn't have the linker scripts or bootloaders ready to go yet.
Incredible work! I'm learning from 0 and have gotten a few sketches working. I'm a long ways off from writing drivers though! Is it possible to find these on breakouts? I'm biting off far too much in one go and making something very silly.
Bitluni, could you work with lilygo and make a variant of this for their wildely popular t-display?
After 4 years, still, this is one good solution, because ESP32-S2 supports a single device only, so mouse and keyboard cannot be connected even using a USB hub.
Hey great project bitluni ! Do you think an esp32 is good enough to connect a usb webcam through the CH559 and use a lcd screen to show a video from it ?
the case is cool. any pointers how to design a split case like that?
Hi, Bitluni, great work. Any chance that it can be used as pure USART to USB bridge for control a 3d Printer ? Mirko
Are there any chances you could share the schematics? It would be very helpful :)
Nice job. But is there a specific reason for not using a MAX3421E-based USB host shield?
I think the 3.6/4.6USD price for a complete mini/full-size board (incl. shipping) is reasonable, especially as there are ready-made and tested Arduino libraries for this that support HID devices, ADK, CDC ACM, PL2303, FT232, BT HID, SPP, mass storage, and also PS3/PS4/PS Buzz/Wii/Xbox controllers, among other stuff.
Using that razor blade on the 3D printer gave me a shock.
Фантастика
Have you considered the ESP32-S2 chip? It is single core with usb otg (USB PHY 1.1) built-in. I would like to see you investigate it for using off-the-shelf usb hardware (webcam, game controller, keyboard, etc.) designed to work with generic drivers.
mantap
When you threw those midi controllers on the table, my heart sank.... :D
Thanks for the video! really interesting... Do you have these USB wings for sale? I'm hoping to use the ESP32 to forward USB traffic to another host (wish me luck) this board would be a great starting point.
Это реально круто!
У русских блогеров на подобную тематику почти что ничего нет...
Really nice! I designed my own board based on your instructions, but when I hold the button to enter the programming mode and plug in the microcontroller, windows says it cannot recognize the device... I tried to install the CH340 driver, but still not works. Could you help me a bit? Best regards, Caio.
What flux do you use on the surface mount?
At minute 3.35 you used a ultrasonic cleaner. Please may you give me info about time, temperature and liquid type used for cleaning? many thanks
Hi Bitluni, Would it be possible for you to share the circuit diagram for CH559 HID that you are using?
What solution did you clean the boar in with your ultrasonic cleaner and for how long?
Do you think it would also be possible to build an PTP-driver so it's possible to communicate with (e.g.) DSLR-cameras?
Nice job! I noticed that unlike the MAX3421E, the CH376S has no built-in ESD protection. Does the CH559 have internal ESD protection?
No clue.. maybe someone else can answer this. That's really built to the dollar so I can keep all the GOLD to myself 😂
@@bitluni 🤣
EDS protection is cheap. I would look at both a viable solutions. ESD protection must always be a major consideration when designing to protect against silly failures.
You have a nice computer desk. Did you build it yourself?
Thanks for the video, but where did you get the mini CRT screen ?
Ebay.. cheap mini color crts are harder to find
do you think we can use this to get acoustical data from a USB microphone (such as ATR2500 usb mic)? Thanks!
Super, bin echt beeindruckt. Was würde denn deine Konsole kosten ? Wenn ein anderer(du) sie lötest ?
oooh now i know why it’s called wchusbserial :D
