Arduino UNO R4 WiFi, RA4M1, ESP32-S3

Arduino UNO R4 WiFi, RA4M1, ESP32-S3

Product information:

The Arduino UNO Rev4 WiFi combines the processing power and exciting new peripherals of Renesas RA4M1 microcontroller (R7FA4M1AB3CFM#AA0) with the wireless connectivity power of Espressif's ESP32-S3.
The memory of the UNO R4 WiFi is larger than its predecessors,
with 256 KB flash, 32 KB SRAM and 8 KB EEPROM.
Furthermore, the UNO R4 WiFi offers a built-in 12x8 LED matrix, Qwiic connector, VRTC and OFF pin, covering all potential needs that makers will have for their next project.

With the UNO R4 WiFi you can easily upgrade your project and add wireless connectivity to extend the range of your current installation. If this is your first project, this board has everything you need to spark your creativity.
