Asked by Mikeburton_2000 on 2019-10-31 03:51:46
dritske Withthe jumper you can power the relay module by the power of the microcontroller pcb. (control pins not isolated) Without the jumper VCC will get its power from the microcontroller and the JD-VCC from an external power supply. (this way input control pins are isolated from the relays).
