This relay module shield provides isolated control channels for switching external loads from microcontroller signals. Optocoupler isolation reduces interference between control logic and high-voltage circuits. Choose the channel count and supply voltage that match your project requirements, and verify the module version for supported input voltages.

Safety Notes:
This product contains electronic components and requires correct wiring and rated power supplies. Always disconnect power before wiring or servicing and verify the supply voltage matches the module specifications. Keep the module away from moisture and extreme temperatures, and ensure proper insulation when switching high voltages. Not a toy—keep out of reach of children.
