11.2 Pin Voltage
The general operating voltage for UNO R4 WiFi is 5 V, however the ESP32-S3 module's operating voltage is 3.3 V.
Note: It is very important that ESP32-S3's pins (3.3 V) do not come in contact with any of the RA4M1's pins (5 V), as
this may damage the circuits.
11.3 Pin Current
The GPIOs on the R7FA4M1AB3CFM#AA0 microcontroller can safely handle up to 8 mA of current. Never connect
devices that draw higher current directly to a GPIO as this may damage the circuit.
For powering e.g. servo motors, always use an external power supply.
