Hi, I have the 8 Channel wifi relay module - https://www.athom.tech/blank-1/8ch-inching-self-lock-relay
Please can someone confirm the wiring for power? There is 7-28v gnd and 5v.
I presume I can either power from the 7-28v and gnd OR 5V and GND?
Can I also take power from 5V if powered from the 7-28v? ( for example if i want to run some led lights that are 5v, but my PSU is 12V can I power the leds from the 5v and gnd?
