Arduino UNO R4 WiFi – Renesas RA4M1 / ESP32-S3 – Wi-Fi, Bluetooth, USB-C, CAN, DAC, OP AMP, Qwiic Connector, 12×8 LED Matrix
The Arduino UNO R4 WiFi combines the processing power and exciting new peripherals of the RA4M1 microcontroller from Renesas with the wireless connectivity power of the ESP32-S3 from Espressif. On top of this, the UNO R4 WiFi offers an on-board 12×8 LED matrix, Qwiic connector, HID support, VRTC, and OFF pin, covering all potential needs makers will have for their next project.
Expanded memory and faster clock with extra on-board peripherals: The UNO R4 WiFi empowers you with increased memory and a faster clock speed, enabling more precise calculations, effortless handling of complex projects, and the ability to tackle demanding tasks with ease. Additionally, it introduces a range of on-board peripherals, including a 12-bit DAC, CAN BUS, OP AMP, OFF pin, VRCT pin and Qwiic connector, providing expanded capabilities and design flexibility.
Hardware compatibility with UNO hardware and larger input voltage range: The UNO R4 WiFi maintains hardware compatibility with the UNO form factor and operates at 5V. It now supports a wider input voltage range, up to 24V, enabling seamless integration with motors, LED strips, and other actuators. This allows for easy porting of projects developed with previous UNO form factor boards and simplifies projects by utilizing a single power source.
Wi-Fi/Bluetooth and Arduino Cloud compatibility: The UNO R4 WiFi combines an ESP32-S3 coprocessor for seamless Wi-Fi and Bluetooth connectivity. It frees up the RA4M1 microcontroller for other tasks. With built-in Wi-Fi and Bluetooth, makers can create IoT projects, benefiting from standardized APIs and existing projects. The UNO R4 WiFi is fully compatible with Arduino Cloud, allowing remote data storage, interactive dashboards, Over-the-Air uploads, and variable sharing among boards.
LED matrix creativity: The UNO R4 WiFi boasts a vibrant 12×8 red LED matrix (96 dots) perfect for creative projects, animating visuals or plotting sensor data, all without requiring extra hardware. Users can utilize the provided API and tutorials for manual LED control via sketch code. Access a gallery of pre-made animations and leverage our online tool for easy creation of custom visual effects.

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 12×8 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.

Authentic original Arduino Uno R4.. This version has a high performance ARM based Micro Controller device with well integrated on-chip memory, flash and eeprom, analog interfaces etc. Provides identical interface as a traditional AVR series MCU based boards.. The integrated ESP32 based WiFi and Bluetooth make this a compelling unit for IoT projects.. The 8×12 LED array is superb! Works great with the standard Arduino IDE

Die R4-Serie von Arduino ist einfach ein Traum. Endlich kann man die Features der ESPs nutzen, ohne eine zusätzliche Buildstruktur zu brauchen.
Die Arduino-Libraries haben einfach eine deutlich größere Community und sind daher besser gepflegt. Allerdings gibt es noch keinen 100%igen Support. So funktionieren bspw. die 433-Mhz Libraries noch nicht auf der neuen Architektur.

Not showing in Arduino IDE even after installation of driver … Buy at risk Packaging is good but defeated 😞

This thing is tiny, packs a load of goodies into that small footprint. I absolutely love the 8×12 redwhite led matrix
