Product Reference Manual
SKU: ABX00087
Description
The Arduino® UNO R4 WiFi is the first UNO board to feature a 32-bit microcontroller and an ESP32-S3 Wi-Fi®
module (ESP32-S3-MINI-1-N8). It features a RA4M1 series microcontroller from Renesas (R7FA4M1AB3CFM#AA0),
based on a 48 MHz Arm® Cortex®-M4 microprocessor. The UNO R4 WiFi's memory is larger than its predecessors,
with 256 kB flash, 32 kB SRAM and 8 kB of EEPROM.
The RA4M1's operating voltage is fixed at 5 V, whereas the ESP32-S3 module is 3.3 V. Communication between
these two MCUs are performed via a logic level translator (TXB0108DQSR).
