Arduino UNO R4 WiFi - clone

This Arduino UNO R4 WiFi clone is equipped with the powerful Renesas RA4M1 microcontroller and an ESP32-S3 module for wireless connectivity. Just like the original, this board operates at 5V and retains the classic UNO shape, making it directly compatible with existing UNO R3 shields and accessories. You get more memory, a faster clock frequency and useful extras such as a 12x8 LED matrix, Qwiic connector, DAC, CAN Bus and OP AMP. Thanks to the built-in Wi-Fi and Bluetooth via the ESP32-S3, you can easily connect to online platforms such as the Arduino IoT Cloud. The wide voltage input of 6–24V makes it easy to control motors or LED strips from a single supply. Perfect for those looking for more possibilities in a familiar package, but without the higher price of the original version.
