Notes:
1. P: power supply ; I: input; O: output; T: can be set to high impedance.
2. GPIO2, GPIO8, and GPIO9 are the strapping pins of the ESP32-C3FN4 chip. During c
hip power-on and system reset, the strapping pin controls the chip function according to t
he binary voltage value of the pin. For the specific description and application of the stra
pping pins, please refer to the chapter on strapping pins in the ESP32-C3 chip manual .
3. The power supply mode is Micro-USB interface power supply (default), 5V and GND
pin header power supply, 3V3 and GND pin header power supply.
