Discover the Arduino UNO R4 WiFi, a powerful and versatile board with WiFi connectivity, perfect for your IoT projects and advanced prototyping needs.

Features:

The Arduino UNO R4 WiFi is an innovative microcontroller board that combines a 32-bit Renesas RA4M1 processor with built-in WiFi interface, an LED matrix, an RTC circuit, and a Qwiic/Stemma QT connector.

Thanks to its powerful processor and WiFi connectivity via the ESP32-S3-Mini module, this board is ideal for connected projects, offering superior processing power while maintaining compatibility with your projects based on the classic Arduino UNO.

The USB Type-C port allows for easy programming and convenient power supply, while the HID interface enables the board to function as an input device (keyboard, mouse, etc.).

The I2C connector makes it easy to connect modules and sensors from the Qwiic and Stemma QT ecosystems, making this board extremely versatile for IoT project development.

You can program the Arduino Uno R4 WiFi board directly in the dedicated Vittascience interface.
