ArduinoUNO 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 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.

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!

Perfect small size. Speed is good for all my son’s projects. Arduino has great build quality. Design is simple and easy to use for learning and fun for all.

Great UNO board with Wifi and integrated 8x12 dot matrix display. Easy to use display which is great for developing your application. I use it to show info on the actions of my app.

The Arduino with Wi-Fi did exactly what I needed it to do. Pairing it to Wi-Fi was one of the easiest things ever much easier than I expected. The response time from my app to the Arduino is nothing. Packaging is beautiful. The item is perfectly packaged. Everything is very clean and safe.

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.

Came in good condition with no broken parts.

Exactly as described and got here super fast. built extremely well absolutely worth every penny fits perfectly with my projectAnd the instructions are super easy to follow
