The 1 Channel 5V Relay Module with Optocoupler lets Arduino, ESP32 or Raspberry Pi switch high-power AC or DC loads like lights, fans and pumps.
The 1 Channel 5V Relay Module with Optocoupler lets Arduino, ESP32 or Raspberry Pi switch high-power AC or DC loads like lights, fans and pumps. The optocoupler isolates the controller from the relay coil, and screw terminals make wiring easy.
