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!

Love working with this board. Easy to program and very functional.

Works super. You need to add simple command interface through com port that will let you set up wi-fi. Then create an http host for your interface. No need to physically wire up switches or buttons or dials. Remember no blocking code. I can see why people use these as Christmas tree light controllers. I can think of a dozen uses for this thing right off. A note on the http interface. Only allow two or three channels at most. There's just not enough RAM to support anymore. Since there's absolutely no room to store anything like a graphic. I created a public facing folder on my Google Drive and put my Graphics assets there and then have the http interface access those through a link so that it doesn't have to store the graphic locally. The only thing that should be stored on the EEPROM is the Wi-Fi setup information. Everything else should be stored on the client's machine AKA your laptop connected to the host running on the Arduino. $$$ BE AWARE! The Visual Studio extension is NOT free. $$$

Purchased this for a couple of projects. It has been both fun and educational.

I bought this for an Arduino/RPi combo for a upcoming project. The Uno R4 boards haven't had enough time to mature, but the libraries are getting updated here and there. The package arrived on time, only undamaged because I ordered it with other purchases after reading that it comes in a package thinner than a cereal box and no protection for the pins. That turned out to be true so I'm glad I followed that advice. It's a bare card, it doesn't even come with a USB-C cable but I already knew that, and I have plenty of cables from other devices. The R4 board itself looks great, clean solder joints, everything assembled straight, clear screen printing on both sides of all the pins. After plugging it in, Arduino IDE recognized it and installed files for it. The "blink" sketch has come a long way with the itty bitty, blinding 12x8 LED array. All said, it's well made, loaded with new tech to explore and well worth $28.50. I would recommend this for anyone interested in Arduino development.

Worked as expected! Its just like a R3, way more powerful with built in WiFi, which is amazing to see from an Arduino. The only problem i encountered is then when i tried to update the connectivity firmware, it bricked the device, so I had force update the chip and get help from the discord, so I'm traumatized of ever trying to update it again, but the support was helpful! FYI, this happened when i was at the final part where it told me to unplug and re plug my device, and i did that, left it, left it there until it said the update failed, and my R4 WiFi was appearing as a generic ESP32 and sketches nor firmware couldn't be flashed to it.

Works great for any project

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.

Funciona!

Très bon produit fonctionne parfaitement

Nonostante avessi già 4 arduini ho deciso di comprare questo che era l’ultimo, che lo ho da ormai 8/9 mesi e lo tengo parecchi stretto, la matrice led è un ottima idea per visualizzazioni semplici e in progetti più complessi banalmente fa risparmiare minimo 2 pin, anche se non sembra, al buio lascia vedere numeri e lettere completamente comprensibili, anche l’usbc è stata una bella evoluzione insieme al Wi-Fi.
