The Arduino® UNO R4 WiFi is the first UNO board with a 32-bit microprocessor and ESP32-S3 Wi-Fi® module (ESP32-S3-MINI-1-N8). The device uses a Renesas RA4M1 series microcontroller (R7FA4M1AB3CFM#AA0) with a 48 MHz Arm® Cortex®-M4 CPU. The UNO R4 WiFi has more memory than its predecessors, with 256 kB flash, 32 kB SRAM, and 8 kB EEPROM.
The RA4M1 has a set operating voltage of 5 V, whereas the ESP32-S3 module operates at 3.3 V. The two MCUs communicate using a logic-level translator (TXB0108DQSR).
