How to Use:
1. This module is triggered at high , and the pin header label on the board is GND (RGND)
2. 5V is the negative and positive pole of the 5V power supply of the relay, CH1, CH2, CH3 are the control ports,
3. High triggering, that is, after the module is powered, the control port receives a high relay and turns on
