What's the point of the RA4M1 if you already have the ESP32?
Based on the data sheets the only guesses I have are that it's running at 5V (presumably because Arduino is living in the past), and that it has USB support.
Either way this doesn't seem especially compelling compared to the many ESP32-C3 boards which generally have less enormous form factors and are much much cheaper.
