UNO R4 WiFi [ABX00087] - Renesas RA4M1 + ESP32-S3, Wi-Fi, Bluetooth, USB-C, CAN, 12-bit DAC, OP AMP, Qwiic Connector, 12x8 LED Matrix for Advanced IoT & Embedded Projects

The latest Arduino UNO R4 WiFi board is nothing short of a revelation for DIY electronics enthusiasts like myself. This board is a significant upgrade, featuring built-in WiFi and an integrated 12x8 LED matrix, which I found to be exceptionally useful for my projects that visually display data or status information.One of the standout features of this board is its connectivity. With both WiFi and Bluetooth capabilities, the possibilities for networked and IoT projects are vast and exciting. I was able to connect easily to the internet and other devices, which expanded what I could do with my projects. The addition of USB-C for power and programming also makes the board more future-proof and user-friendly.The quality of the board is exactly what you would expect from Arduino—robust and reliable. The performance is stellar; I've used it to create everything from simple LED displays to more complex networked sensors without a hitch. The integrated OP AMP and DAC are great for more advanced applications requiring precise analog and digital conversions.The documentation provided by Arduino remains top-notch, making it easy to get started and to troubleshoot any issues. I particularly appreciated the inclusion of the Qwiic Connector, which simplifies adding a wide range of sensors and peripherals without soldering.Overall, the Arduino UNO R4 WiFi is an excellent choice for anyone from hobbyists to seasoned makers looking to explore the capabilities of connected devices. It’s a versatile, high-quality board that offers great value for money and opens up a new horizon of possibilities for creative projects. Highly recommended for its performance and ease of use!

The Arduino UNO R4 WiFi is an updated version of the classic Arduino board. What makes it special is that it’s faster and already comes with Wi-Fi and Bluetooth, so you can connect your projects to the internet or even control them from your phone. It looks almost the same as the older Arduinos, so you can still use the same cables and accessories. It also has a little LED matrix (like tiny lights) that you can program to show numbers, symbols, or messages. This board is perfect if you are just starting to learn, because it’s simple to use but also powerful enough to create fun and modern projects like smart devices, robots, or interactive systems.

This chip is amazing. It is easy to connect to WiFi and then you can send commands to it just by typing in a URL.

What can I say, it is a development board. It arrived in good condition, and works as expected. No surprises.

Great device for DIY projects and expanding your horizons if you are older, like me, and want to see if you can still learn some new tricks.

I mean there isn’t really much to say, I used it and it performed well. The only caveat is that it isn’t able to perform fast enough for my rotary encoders. I optimized my coding as much as I could and I could get about two working at max rotation speed. I had five to test out and it worked okay until I tried three. They stopped reading some of the updates and began to register positive numbers only when I rotated the knobs slowly. The display screen works perfectly though. I feel that things that need to get new update states as frequently as possible to work well is not really the best way to use this. But it still works very well and I can just have the knobs change to negative or positive with a single knob since I have so many. Overall, great microcontroller. I still haven’t tested out the wireless transmission or built-in leds yet so hopefully when I get to that it will work as it should. Very great. The hardware is well built and soldering is as expected. Currently I am testing out an led strip controller with knobs and a display screen and that is working well so far. Very nice.

I bought this as an intro to coding and electronics and I love it. Super fun to learn and program. If you want an intro to this kind of stuff this product is definitely a good way to do it. Overall quality is fairly good, however I could see some problems with the power port as it does feel a fair but cheaper than the usb-c port. It is on the larger side, coming from an esp32, but it doesnt seem to be an issue. I recommend buying a case to protect it in case of a fall. Overall great product and highly recommend for anyone interested.

Perfect condition, high quality, good price

De arduino is beschadigd aangekomen

Der Arduino ist wie gewohnt ein tolles Board für kleine Projekte. Die neue Generation mit Arm Cortex M0 ermöglicht nochmals deutlich mehr Projekt im Vergleich zum 1. Version. Der Preis dafür ist akzeptabel. Einziger Kritikpunkt bisher: ich hatte Probleme den USB-Port dem Board in der IDE zuzuordnen bzw. die Verbindung wieder zu löschen. Es gibt dafür Workflows im Internet, die allerdings recht unhandlich sind. Versand wie fast immer bei Amazon schnell und zuverlässig

Funciona!

Arduino é sempre una garanzia, rapporto qualità prezzo ottimo, é fantastico per imparare le basi della programmazione, la matrice di led permette anche di divertirsi con animazioni e disegni anche solo con la scheda e un cavo

Très bon produit fonctionne parfaitement
