Features
- Dual-Core Processing with Renesas RA4M1 and ESP32-S3: The Arduino UNO R4 WiFi combines the Renesas RA4M1 microcontroller (ARM Cortex-M4) and the ESP32-S3 Wi-Fi/Bluetooth chip, delivering powerful dual-core processing capabilities. This combination offers flexibility for a wide range of projects, from high-speed communications and wireless control to real-time data processing and edge AI applications.
- Comprehensive Wireless Connectivity: Equipped with Wi-Fi and Bluetooth 5.0, the UNO R4 WiFi ensures robust wireless communication for IoT projects, remote sensors, smart devices, and wireless control applications. Whether connecting to the cloud, other devices, or local networks, the board offers stable and high-speed wireless connectivity for seamless operation.
- Modern USB-C, CAN, & Qwiic Connector: The USB-C port enables efficient power delivery and fast programming, improving ease of use compared to traditional USB connections. The Controller Area Network (CAN) support allows for reliable, real-time communication in industrial, automotive, or robotic systems. Additionally, the Qwiic Connector makes it easy to add I2C sensors and peripherals, simplifying the connection process and reducing the need for complex wiring.
- High-Precision 12-bit DAC & OP-AMP: For projects that require high-quality analog output, the 12-bit DAC (Digital-to-Analog Converter) and integrated operational amplifier (OP-AMP) provide precise analog signal generation and amplification. This feature is ideal for audio projects, sensor interfacing, or applications where analog signal control and processing are necessary.
- Integrated 12x8 LED Matrix: The UNO R4 WiFi includes a built-in 12x8 LED Matrix, enabling users to display dynamic visuals, messages, or real-time data on the board itself. This makes it perfect for projects that require immediate visual feedback, such as status indicators, event displays, or interactive user interfaces.

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!

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.

I literally love arduinos. I will tell you when I first started I bought the clones. They are cheaper but more aggravating. They are legal because its open source. You can use arduino ide to program them but it's tricky setting up the com ports or gettting them to read correctly. These are really not that much more and are the real thing designed with IDE so without a doubt they work flawlessly and your supporting the people you should. I will definetly be sticking to the real arduinos from now on. I use these to prototype things, make projects with my kid and teach her about electricity, programming, building. It's just a great time. I even gave them out as presents at work. I will say I use tinkercad online for free. They have arduinos in their circuit designs and you can build and simulate projects prior to the protoype build. This just helps minimize issues, not short anything, or helps you learn as they have great details for different sensors and how to connect them. Or maybe you want to build something that you do not have a sensor for. Build it in tinkercad and make sure it works as you want it to prior to buying a sensor.

Amazing! I was able to build my prototype for a company I’m working on, I only had one problem though which were the keys they were a little bent but that didn’t bother me much because I was still able to assemble and put it together with a kit I bought!

Arrived brand new in box, as listed. The board and embedded LEDs both work. Very happy with the purchase.

The WIFI and Blu-tooth add to the utility of the R4 board. Be careful though as max amp draw has been reduced.
