Description
Arduino UNO R4 WiFi Development Board
The Arduino UNO R4 WiFi Development Board is the next-generation Arduino UNO designed for makers, students, engineers and IoT developers. Built around the powerful Renesas RA4M1 32-bit Arm Cortex-M4 microcontroller, it delivers significantly higher performance than the classic UNO R3 while maintaining the familiar Arduino UNO layout and 5V operating voltage. It also includes an ESP32-S3 module for Wi-Fi and Bluetooth® Low Energy connectivity.
One of its standout features is the integrated 12×8 LED matrix, which allows you to display text, icons and animations directly on the board without external hardware. The board also includes a USB-C connector, 12-bit DAC, Real-Time Clock (RTC), CAN Bus, Qwiic connector, and improved debugging capabilities, making it ideal for robotics, IoT, automation and embedded development.
The Arduino UNO R4 WiFi is fully compatible with the Arduino IDE and Arduino Cloud, enabling rapid development of connected applications while preserving compatibility with many existing Arduino UNO shields.
