It features a RA4M1 series microcontroller from Renesas (R7FA4M1AB3CFM#AA0), based on a 48 MHz Arm&reg; Cortex&reg;-M4 microprocessor. The UNO R4 WiFi&#39;s memory is larger than its predecessors, with 256 kB flash, 32 kB SRAM and 8 kB of EEPROM. The RA4M1&#39;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).</p> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <table style="font-family:&#39;Open
