VB: When VIN is input, VB outputs 3.8V and can be suspended; When VB is used as input, it is directly connected to the module power supply with an input voltage of 3.3~4.3V
VIN: Power input positive pole, supports 5-16V input.
GND: Negative pole of power input.
TX: The main serial port sending pin has been pulled up to 3.3V.
RX: The main serial port receiving pin has been pulled up to 3.3V
EN: default to EN (core board power enable pin), internally pulled up to VIN
When the EN is low level, the power is turned off (when the external transistor driver module EN is high level, the power is turned off). If not in use, it will be suspended.
RDY: Socket 1 connection status indicator, high level indicates not connected to server, low level indicates connected server
D/P module on/off (automatically powered on by default), can be suspended when not in use
