Introducing the Arduino UNO R4 Minima & WiFi

[@fred.chapman]

@elektortv Clemens Valens, thank you for your excellent introduction to the new *Uno R4 Minima* and *Uno R4 WiFi* boards! Your succinct explanation of how R4 improves on R3 and how Minima and WiFi differ from each other is filled with valuable information. I'm very interested in electronic musical instruments, so the enhanced analog signal processing capabilities of the R4 are quite exciting to me. In addition, the R4 WiFi is supported by the *Arduino IoT Cloud* platform, which makes it easy to build wireless remote control panels and shared data dashboards. Great stuff all around!

I think it would've been butter if they replace the LED matrix with OLED display .

r4 is pretty good. but the popularity, the uno r3 get is just another level. the uno r3 & it's clone boards & the atmega328p chip will never be useless due to there simplicity & effortableity. i just loved uno r4, but r3 is a milestone...!!! love arduino...

[@LivingTheDream77]

R4 is 32 bit and R3 is 8 bit. Its simply game over for R3

[@AkashBagFEce]

@@LivingTheDream77 many people use to do simple projects, copy of re ar so much available in market that r3 will never lose it's popularity...

[@bumpedhishead636]

R4 is cheaper than the R3. That will drive people away from the R3.

[@KennethScharf]

according to the processor spec sheet, it might be possible to overclock the R4 to 64mhz.

Cool and informative video shot, thanks for sharing it, keep it up :)

The main thing going against Arduino devices and their clones is that there are more powerful options available that are much cheaper, they still work with the Arduino IDE but can also be programmed using languages such as Micropython, Go and Rust. The 5V logic makes sense as it will work with existing accessories and is a simple project swap-out but other 3.3V boards are easy enough to adapt using logic shifters. It's good to see Arduino evolve but one thing I like about the Uno R3 is that you can prototype on it and then just flash the 328 chip and dispense with the rest of the board.

Have you looked at the full product line? the 8bit line of products is no longer representive of what we do. This product is a logical progression of the one product we've been making for 13 years but it doesn't represent the whole Arduino product line which include industrial products with dual core Cortex M7 processors

Well put Massimo

@@supermodernotv An M3 screw inserted in the top-left mounting hole will still collide with the (SCL ...) header in this new revision. Wish this had been fixed. I'll have to continue cutting the head of a nylon screw to fit. Anyway, look forward to trying out the new features.

[@mikewillis1592]

@@dd07871 Yes - about time they fixed that layout error made way back when. A Nano version would be a nice addition, or at least a board that can sit on a sensible header so it can be used on a PCB. Rectangular, proper mounting holes, no weird 0.05" offsets and so on. The Nano every goes part way but the other new Nanos are a bit different. Closet is the Nano IOT 33 but that is a bit limited by the form factor and 3.3V. Perhaps a 40 pin nano might help there.

Be logical when repairing! Great video!

[@ElektorTV]

Always!

[@Elektronik-1]

The "auxiliary processor" Esp32-s3 has about 10 times the computing power of the RA4M1 CPU. Can this also be used with the Arduino ide?

[@kb3cxe]

I am a BIG fan of Arduino, but now I am the sad owner of some 12+ printer cables thanks to the new data cable change. Why????

[@Breadts1cks]

Because those fat ugly cords are a PIA lol

[@jackflash6377]

Can it run GRBL ??

[@h49suthar]

Ofcourse it can ,even Uno R3 supports GRBL commands. Most processing happens on PC , microcontroller just convers serial data to stepper motor pulse nothing else...

[@jackflash6377]

@@h49suthar Thanks for that but I don't think you understand the root of my question. Controlling steppers or servos requires pulses at certain frequencies. Events in timed sequences. Using a faster CPU can cause timing problems which can affect timed events and pulse frequencies. Of course you can control PWM output by using the PWM ports but can you control internal timed sequences that rely on CPU speed?

[@h49suthar]

@@jackflash6377 @jackflash6377 oohk ,now I understand your concern. I have just checked, GRBL uses time library only for atmega series chips. It will require alot of modification in order to use Uno R4. New library is yet to release...

[@dd07871]

grblHAL is available for RP2040/raspi Pico and ESP32.

[@entmontage]

No, grbl doesn't compile for the R4: kzbin.info/www/bejne/iHOvZKesiZuniLc

[@Cen_t1369]

bro please I can't find this anywhere... can the r4 be connected from the normal android charging cable?

[@turbocuber]

If you consider usb c as normal Android charger , the yes , just don't use a fast charger
