Relay boards let a microcontroller switch lamps, pumps, fans and other high-power or mains loads: 1, 2, 4, 8 and 16 channel 5V modules, 12V modules with high or low trigger, 3V relays that work directly from an ESP32, optocoupler-isolated boards, OMRON solid-state relay modules, the XY-J02 timer relay and an overcurrent protection module.
Which relay module?
Match the coil voltage (3V, 5V or 12V) to your supply and check the contact rating against your load. For frequent switching or silent operation, a solid-state relay has no moving parts. Mains wiring is dangerous: keep it in an enclosure and get it checked if you are unsure.
