  • A Maker's Dream: Arduino UNO R4 WiFi Review
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! ... show more

  • Great Arduino for teaching the kids
It is an Arduino-branded product and a nice quality board for using with Arduino projects to teach the kids programming and how these work. It is sometimes hard to find these at a decent price, but it is a worthwhile investment if you want to learn how to program these or even use them for projects around the house. Some of the knock-off brands have issues with the boards, and I have yet to have a problem with an Arduino. If you are newer to the Arduino world then it is also good to note that if you purchase an Arduino-branded product, it works easily and quickly with the Arduino desktop software, so there is minimal need to go and search for the device to get it up and running. ... show more

  • Great board for a variety of uses!
As my first Arduino board, I did not really know what to expect. However, the capabilities of my Uno R4 have been pretty great! The built-in Wi-Fi and Bluetooth make it really convenient and easy for certain projects, and the LED matrix is also fun to tinker with. Everything works as expected, the documentation is excellent and easy to grasp, and overall this is a great product. It's a hobbyist's dream, but I can see this being very useful for a variety of ECE-related projects. ... show more

  • Awesome little board
The new Arduino Uno R4 is great. All my R3 stuff works perfectly with it. Got the one with the LED Matrix, it turns out it's more of a novelty than a useful addition. Still figuring out the WiFi part, but it seems like it works well.

  • Excellent controller
I'm only giving this 4/5 because it did not come with a usb-c cable. Otherwise great product I've put a lot of mile on mine already.

  • Lots of fun!
This is the version with WiFi, and there are plenty of tutorials on how to connect to your WiFi network and make a REST call. It uses C since its an embedded device and its actually kind of fun relearning the gotchas in C, reminds me of college. The arduino IDE makes it really easy to reflash the device to test changes incrementally. ... show more
