Somehow, this video made 20 times more views than my previous videos, and it made me double my number of subscribers! So thank you again to everyone who watched, commented and subscribed! This video was released only a few days after the release of the boards, so let me give some updates: - First, the R4 WiFi is now compatible with Arduino IoT Cloud: blog.arduino.cc/2023/07/12/introducing-uno-r4-wifi-support-in-the-arduino-cloud/ - I was able to run a debug session on the R4 WiFi using Platform IO without any external hardware For those who asked for an in-depth review or more code examples, here some nice reviews made by other channels that I've found : - @Dronebotworkshop: th-cam.com/video/kJE9CBb3fT8/w-d-xo.html - @adafruit : th-cam.com/video/uw0EU8urz5M/w-d-xo.html - @esp32 (in Spanish 🇲🇽) : th-cam.com/video/HQ4J0-3RN7c/w-d-xo.html
We need a basically 328P refresh drop in chip from Atmel, still 5V, more memory, more ram, higher frequency, maybe better ADC, DAC etc... Uno need this, not that microcontroller from Renesas
Merci ! I don't speak French ha ha . I wish I could understand your very fast English accent. Thanks goodness for the closed captions. I appreciate pointing out issues in the tutorials that can cause problems.
What I missed in the video is compilation time. In my classroom, compilation time is key. For a Leo, MEGA or UNO it is near instant, compilation for a Microbit is also very fast, Teensy ditto, but for M0/M4 boards is was much slower, and for ESP32 it is unbearable slow (1 minute compilation time!) I do not agree about the confusion with Serial and Serial 1, we use Leonardos for ages, because they have dual UART, which is a must have for GPS, GSM, MIDI and stuff like that. I also hope they kept SPI exclusive to the ISCP header, and no wiring through pins 10-13 as well. Another reason I prefer the Leo over the original UNO: you have extra pins and easier SPI hookup. I also quite often use the 6 extra analog inputs on the LEO, especially for multi-analog-stick gaming projects many students make. I actually dilike USB-C, as the port dies easily in classrooms, and USB-B can be soldered by hand easily, USB-micro is doable as well (1mm spacing), yet USB-C connectors need a reflow machine for repair.
Regarding the LED matrix in the R4 WiFi, it looks fun but I wonder how many projects will use it (specially when the board is inside a box or you use a shield). I think this kind of functionality should be on a shield not in the main board.
It seems Arduino is trying to get involved into 32bits world. But, I think it would be very difficult to beat ESP32 and RASPEBERRY PI Pico. They are really cheap and very well documented.
@@argvSys You can perfectly use it for prototyping, and move code to a Pico when the project is finished. In that phase overkill and expensive are very different. You probably don't deal with a classroom. ESP32 is not suitable there.
@@lovemadeinjapan Oh, ok. I thinked you were refering to hobbyst projects and not a classroom. For prototyping, any board is useful, but students will never use the full resources of a Pico or an ESP (or even this thing called """UNO""" R4) in the first place (unless they program them in the Arduino IDE), so why to get the bigger thing? Also, MicroPython exists, so presentations should not be a problem since its an interpreted language, and when they finish the project, translate that to C++. ¿Why ESP is not suitable for classrooms? Just wondering.
@@argvSys Compile time. They can click compile maybe 3-4 times in a lesson of 45 minutes. With the M4/Teensy/Leonardo it a matter of seconds. Maybe it could be in Micropython, but I don't see fit for that language in the language tree.
I really like the new dual serial! That was one of my reasons to use Arduino Mega. When I set up the companion controller as HID, I had to use soft-serial, or Arduino Mega to connect a serial terminal.
For advanced users, a lot of confussion, for beginners, they still will use "digitalRead(1)" so. . . the troubles will start at deprecated libraries using AVR instructions :,D I had to get a Leonardo even when I had a Zero because they didn't work on the Cortex architecture. About analogWrite I ever had that problem, they should name it pwmWrite to avoid confusions. I like how in mbed they have AnalogOut and PwmOut to be clear what do each.
Thank you for the information. Like I wrote in another video the worst thing compared to the R3 is the max current for an output, 40mA as you said in the video, and 8mA on the R4. So you will always need transistors or small relais to command an actuator. So more hardware needed. That's a pity.
thanks for the review ! I was really interested in the LED matrix ( for tamagotchi reasons :3 ) Can't wait for your feedback about the future wifi features ;) btw, excellent video format, love it !!
What confuses me, is the use of an ESP32 for WiFi on these things... when the ESP32 is a more capable microcontroller in its own right. Am I missing some big obvious thing that makes this logical? Or shouldn't they have just used the ESP32 as the main processor?
you're right, the ESP32 is a really powerful microprocessor that's even more powerful than the arduino R3 but the dealbreaker is that when you upload a code to it from the arduino IDE it has to be written to it's flash memory and it can take like 20-30 seconds just to run a simple blink code for example and thats why arduino's are more preferred
The reason is financial, not technical. Arduino has a business relationship with ARM, so all new Arduino boards have an ARM processor as the main chip. The ESP32 uses a chip from Tensilica which is a competitor to ARM so is only allowed to be used as a peripheral device to provide WiFi etc.
You're not really thinking about efficiency if you're using the Arduino IDE and such, so honestly it's not the worst of ideas to leave a bad WiFi code to be written in a dual-core wifi+BL chip and leave some application code to a cortex M4. I'm not so sure that a single xtensa core is faster than an M4 tho Also, should add that people generally dislike both the ADCs and DACs from the ESP32 chips, so the renesas' one should take care of it
The lack of a crystal has rendered the R4 not useable for my turntable projects that are driven by SimpleFOC. Have several old Unos that work superbly, but i tried an R4 and no joy as the speed of my turntable was nowhere near as accurate as with an old Uno.
No "revision" should change the hardware capabilities of a thing. "Uno" means "atmega328 based". If they wanted a new chip fine, but they should then have called it "the Trentamila ventisette" or whatever.
It is a fail no matter what name it has.. What made uno so popular? Usabilitie and low complexity.. Not board are a chaos mixture of their feature set, the led matrix is laughable at best and a toy..
100% with you on about the "revision" not changing the chip. The R4 WiFi released under another name could have been a nice addition to the Arduino product line
I bought an Arduino last week for the first time (after using the Raspberry Pi for decades). The Arduino is lots of fun. I have now a large collection of gizmos (modules) to plug into it, like a kid again discovering something new. I bought it though to tinker with some model railway projects, and discover that because they have changed the two main micro-controllers, the R4 is a different architecture to the R3 and is not compatible with a complex model railway control system that I wish to build. C'est la vie, not a disaster. I'll get the older Arduino Mega for the project, and keep the R4 Wifi for another project. Merci pour la vidéo, nice accent ;)
I find Arduino released this thing without making sure the reference material thoroughly covers the programming differences between this Renesas RA platform and the platform the UNO R3 uses. Does a library environment for this new platform exist? For example, try figuring out the interrupts and the available interrupt types. See if the reference document code for interrupts actually compiles or functions as advertised. See if you can get pin change interrupts working. Please show us how if you manage this. I agree this R4 will be frustrating until the public Arduino community catches up with functioning libraries and documentation having functioning code examples.
Like the led matrix makes it a good attractive tool for educational programming. its about time they did a board with an esp32 and some extra gpio hardware, in the old footprint they could easily do a 32, sdcard slot, rtc, and some 12bit a2d / d2a.
@@kitecattestecke2303 they don't seem to like espessif...... I think it's because everyone jumped on the 8266 and it was a success that they overlooked
Given the main target audience of the UNO boards (beginners/education), I don't necessarily think that having a coprocessor is a bad idea. That way, the network stack run on a completely separate chip and cannot be messed up by bad beginner code. A few years ago it was quite common to use a Nordic NRF5x or an ESP8266 with an UNO to add wireless capabilities even if the "companion chip" was more capable than the 328p
It seems to me that a beginner's development board should have enough current to drive hardware if the focus is not heavy into software like the Raspberry Pi. I personally want to play with components as well as software, but it seems that each board makes you pick between them. Pi is more powerful and is software heavy, but not nearly as easy to learn. R3 is a somewhat limited playground that doesn't include enough power to support PC style interface peripherals. The reason you don't see commercial developers drop what they are doing to use Arduino or RPi has to be a functionality limit that you hit while trying to use them. Bottom line: they are best viewed as a learners' hobbyist toys.
almost all projects in the arduino world require more than enough computing power with the R3. I don't understand the usefulness of this upgrade for the Arduino world, after all if I want to use ESP, I use an ESP... and it costs even less.
Clones probably won't be more expensive after the chip shortage is over. You used to be able to get Arduino clones for about $1.50. Also, sometimes you need 5V IO. Pity the power on the IO pins is down to 8mA, though. Isn't the only reason to buy from Arduino themselves to support R&D and software development? And it can't be good to rely on everything to be made in one foreign country. Good to keep alternatives spread around.
Well as far I see, it does the common job. I'm more interested how stepper control is improving with the new boards. I haven't seen reviews about that.
Kind of not a fan. I'm bothered by the change of architecture. For me, I do not associate the brand name with the formfactor but with the Achitecture. For me Uno means AVR Achitecture. I was already unhappy with the Nano brand switch to ARM (Nano 33 IoT, Nano 33 BLE). Don't get me wrong I have nothing against using ARM chips. By now I used 6 Nano 33 IoT Boards for personal projects. In January made my Arduino Hobby to employment and now work as an Embedded Systems Developer. There I developed with the RP2040 (Raspberry Pi Pico) which too is an ARM chip. But depending on the project an 8bit Achitecture can be superior to a (comparatively) complex 32bit Architecture. But now generally a great product while not attractive to me, I have more than enough spare controllers to last me a couple years and when I used those up I'll switch to custom PCBs.
Haven't started playing with mine yet. Anyone tried this one with Arduino IOT cloud ? Wondering if there is any more success with this board and the cloud agent, which seems to be seriously flawed. I'm not sure if Arduino just isn't into the cloud implementation long term, or if the development is just a little out of their level of ability. This really could be IOT for the masses if they can get on top of the cloud agent issues.
Hello and thank you for your comment. As I said in the pinned comment, I was able to use the R4 WiFi with IoT Cloud briefly, the agent wasn't a big problem for me (I'm using macOS, maybe that's OS specific ?) Have you ever tried Adafruit.IO? I made another video on Adafruit.IO and their no-code firmware (WipperSnapper, currently in beta), their ecosystem seems much more mature and stable for quick prototypes especially for designers/students. Several ESP32 boards and the Pico W are already compatible (the R4 WiFi is not supported yet, but I'm sure it will be in the future), that's my bet for "IoT prototyping for the masses" ;)
I'm glad that they finally brought the Uno to the modern world... I'd be curious to see if someone comes up with a proper library for the board (something like libopencm3).
Entry price excessive and a poor hardware solution for a final product. Better to use a board like the dev kit for CH32V208 which has massive functionality at a very low price, all with one microcontroller and a crystal. The popularity of Arduino does not justify using it any more. The CH32V003 are great too but easier to lock your self out of if you mess up with programming on the swdio pin or oscillator source. My current choice for small stuff though.
Please slow down! I understand English is not your first language, but your fast speech & accent are very difficult to follow. You have excellent content - just slow down!
it's all nice but let's not make it difficult now please! for example I can't work very well with that ESP32 OR!!! a video REALLY needs to show everything step by step and really not skip anything, maybe then it will work with something like ESP32. I am very happy with the simple old Arduinos! ( And honestly, clones too ) Regards Rob

Both are not good IMO. Give me a Teensy 4.0 any time. Such a relief to work with. And 10 times as fast as an ESP32 or Pi Pico.
