Arduino UNO R4: The New Dimension of Making
ฝัง
- เผยแพร่เมื่อ 25 มิ.ย. 2023
- 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.
Get yours!

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

@@bmp7458i think they meant technical specs like flash memory size and whatnot
@@zUltraXO ah.
When a video starts with something abstract like "In a universe of possibilities...." then you know it'll be light on technical details.
I blame apple
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
I was sceptical until it said 20$. The value proposition of UNO is that it’s relatively cheap.
And the wifi has the same price as the old one
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.
this board is compatible with most of the libraries people use and will improve over time. Apple went from Intel to ARM but they didn't rename the macbook... it's still a macbook and not even there everything is compatible. it's a fact of life. we need to move forward.

@@jeffbrownstain that sounds like a security nightmare
@@mbanzi You need to get your ears checked
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.
Anything for the R3 would work with the R4 , no?
@@FronosElectronics yup, but I already have several R3s, so I want to wait until there are some unique projects for the R4
@@FronosElectronics "No, some UNO R3 libraries use instructions of the AVR architecture that are not compatible with the architecture of the UNO R4 WiFi, however there are libraries that have already been ported as part of our early adopters program or are based on the Arduino API." Official answer
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...
Are you by any chance the same one who commented on Instagram? 😂😂
@@lorenzo_de_paolis yes... im the same person 🤣🤣🤣 are you also interested about hobby electronics?
Yess
@@lorenzo_de_paolis then please reply me on the offecial Arduino page post. I use to designe PCBs, and various kinds of small modules related to Arduino. I'm interested to watch your works also...🥰 Reply me on that posts comment
R4 is 50 cents cheaper than R3. What are you talking about ?
Just got mine today! Can't wait to start messing around with it!
i gotta get an R4 wifi can't wait for it to be available again. Thank you Arduino.
Already ordered the product!!!! Excited!!!!
Nice. Looking forward to try some projects with it.
Nice! I'm already using Arduino products for years. 😊🤝
ufff... i was wait for just it!!! it's just wow!!!
Just Wow.. 😍😍 love it!
Niceee 😊
Hope I could try it out some time later!
An excellent board I had ordered it super good
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.
Super excited for this one.
Esp32 - amazing
I love the Content and Video, Got the Inspiration & Motivation to start the Channel of same/similar Content - Thank You Very Much.
Nice shot, thanks for sharing, keep it up :)
Great evolution!
can't wait to see the nano version
That will be so cool 😎
Why don't use esp32 s3 as main core directly?I am confused by design like the.
The main Arduino UNO series have always been 5V to ensure compatibility with even the oldest projects. The ESP32 isn't suitable as it is strictly a 3.3V chip and would be fried if connected to 5V circuitry. Where as the Renesas RA4M1 is one of not that many 5V suitable ARM chips.
@@chielvoswijk9482 Thanks for your reply
@@Robot_Closedand another reason is that Renesas spend Money to let their mcu become official arduino。
Wow esp32 s3 mini
Good product 😊
So hyped 🤙🏾🔥🔥
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.
What about GIGA R1 WiFi?When it's gonna be available?
I can’t get any qwiic devices to work with it.
I wonder why is UNO R4 instead QUATTRO when the main IC change that much.
Se ve bien la placa completa no tan barata pero no tan cara
Libraries made for UNO3 such as grbl will not work with this UNO4 so its not really a uno ???
great job
The more advanced microcontrollers get, the more room there is for a “low level, low power” tool…..
Why the Renesas MCU and not just the ESP32?
5V Tolerance. You can hook the Renesas IO to any existing UNO project with no worries. Where as the ESP32 would just blow up...
How we get that 😊
RAM?
Nice products
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?
genial placa

Is it possible to run micropython?
Still no 5 GHz WiFi... Does anyone know, which year we have now?
It's they year in which 5GHz wifi tends to be more expensive than 2.4GHz. When the price comes down, we will replace the module :)
@@mbanziArduino uno rev4 supporta micropython?
My usb HID isnt working. How come there is no documentation or help, but tons of crap apple marketing ploys?
Go 🌎✈
Waiting 4 the shipment…
I chuckled when I saw that the chip was an EPS32 all along lol... The only advantage of Arduino is just that it has 5v IO compared to ESP32's 3.3v, and that's it (the major one, at least). You can achive same voltage by just using a cheap level converter, less than 1 dollar.
Nope, the Espressif ESP32-S3 is _not_ what powers Arduino Uno R4 boards. The ESP32-S3 is just a Wi-Fi & Bluetooth _coprocessor_ on the Uno R4 _WiFi_ board, while the simpler Uno R4 _Minima_ board doesn't have an ESP32-S3 at all. The WiFi and Minima versions of Uno R4 _both_ use the same main processor: the *Renesas RA4M1* (which has a 32-bit Arm Cortex-M4 core).
One big advantage is that _Uno R4 beats ESP32 on analog signal processing:_ Uno R4 has an analog output with 12-bit DAC resolution and 6 analog inputs with up to 14-bit ADC resolution. Plus, _the Uno R4 WiFi board is supported by the Arduino IoT Cloud platform,_ which makes it easy to build remote control panels and remote data dashboards. So, Uno R4 is definitely _not_ an ESP32 with 5 V logic levels-it's much more! I have big plans for my Uno R4 WiFi.
Background music may be the most irritating crap I've heard so far.
Era hora
Lets hope you did a better job with the next generation of hardware, because you really messed up the Arduino IDE with 2.x
The 2.x IDE is so much better than the previous version, it has things like autocomplete and built in dark mode.
Also, do you mean hardware or software, because what does "messing up the arduino IDE" have to do with the hardware??
@@a-cat if the project considers the trash fire that is 2.x to be an improvement, then I question their commitment to producing a quality product.
@@MrGeekGamer what specifically is bad about 2.x?
miss AVR
I look forward to not seeing them in stock anywhere.
Can’t wait for Jaycar to sell it for $200.
YOO
Can you at least fix the stupid spacing on the connectors already??
It has become a standard. In a kinda accidental way it prevents plugging in the wrong way.
Add a usb C port and its just perfect
It already has one..
The website is incredibly annoying with popups all the time
90% of websites are this way unfortunately...
And it still has that crap linear regulator
what do you mean? it has a buck converter, the linear is only for the ESP32 and you dont need that much, at that level a converter have bad efficiency anyway.
Cloud? No, thanks. That just opens the door to all the security problems that Internet of Things faces. I'd rather not expose my devices to the Internet like that. Please keep that part completely optional.
This video sounds supercheasy, like an Ali Express seller commercial, and the product seems fish nor foul (coprocessor faster than main, 5V with crappy amperage, no use of the extra pins on the chip).... Never got the UNO to begin with (I'm a Leonardo fangirl), but for power I go Teensy 4. And it is ugly too.
wtf are they talking about
nobody speaks spanish or italian btw
My usb HID isnt working. How come there is no documentation or help, but tons of crap apple marketing ploys?
