Arduino UNO R4: The New Dimension of Making

Показать описание

The world’s most popular development board massively scales performance with new 32-bit versions: the UNO R4 Minima and WiFi.

Arduino UNO Minima means technology accessible to everyone offering more computational power, memory and speed in the familiar form factor of the UNO at 5V operating voltage at an affordable price. You can easily upgrade projects made with the UNO R3 or the Leonardo.

UNO R4 WiFi means the same industry-standard form factor at 5V operating voltage, but with the enhanced performance of a RA4M1 32-bit microcontroller by Renesas with ESP32-S3-MINI coprocessor as well as Wi-Fi® and Bluetooth® connectivity, a 12x8 LED matrix, and a Qwiic connector.

Sure why would anyone mention the actual stats of their own product, let's just talk vague constructs

0:59 Good to see Gustavo in the video. His arduino based glove instrument has stuck with me since I first watched his video. Amazing

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?

Feel so great to see the R4 with Wifi version! ❤

Bad naming, Arduino could have called it QUATTRO (or whatever) but keep the same formfactor. Docs, blogs, info etc all will become very hard to direct to the correct "uno" now since they just won't all be compatlibe 100% ! The features are cool though.

Looks awesome! I'll probably get it in a few months when there's a lot more community support and project ideas available for the R4.

I was sceptical until it said 20$. The value proposition of UNO is that it’s relatively cheap.

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...

i gotta get an R4 wifi can't wait for it to be available again. Thank you Arduino.

Just got mine today! Can't wait to start messing around with it!

Already ordered the product!!!! Excited!!!!

oh come on! we have the rpi to do this. the uno was the cheap quintessential and minimalistic 8 bit microcontroller needed for every project. Pretty sure this is just them trying to fill in the gap left by the stock shortage of rpi.

Why don't use esp32 s3 as main core directly?I am confused by design like the.

Robot_Closed

can't wait to see the nano version

Hopefully moving to Arm doesn’t mean future chip shortages. That said looks like a huge leap forward, looking forward to getting one and seeing what’s possible.
