UNO R4 WiFi compatible development board with WiFi, Bluetooth and built-in 12x8 LED matrix

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
The UNO R4 WiFi Development Board combines the powerful Renesas RA4M1 microcontroller with an integrated ESP32-S3 module providing WiFi and Bluetooth Low Energy connectivity. The board keeps the same form factor and 5 V logic as the classic Arduino UNO, making it compatible with many existing shields and accessories.

A built in 12x8 LED matrix with 96 red LEDs makes it easy to display text, symbols, simple animations, status information and sensor values without the need for an external display.

The board features a Qwiic connector for quick connection of compatible sensors and modules using the I2C interface. Qwiic uses a 4 pin JST-SH connector with a 1.0 mm pitch and operates with 3.3 V power and data signals. On board level shifters allow the 5 V main processor to communicate safely with 3.3 V devices.

The UNO R4 WiFi also includes a 12 bit DAC, CAN bus and a real time clock, making it suitable for advanced control systems, IoT applications, data logging, automation and education. The board is easily programmed through the USB-C connector and is fully supported by the Arduino IDE.
