4 Channel Relay Module
It is ideal board to control & switching high current loads like fan, lights, low power heater coils. It not only provides switching but also provides isolation between the power device and your microcontroller. Devices upto 7 Ampere can be switched using this relay. These are 12V relays but can work with any microcontroller, arduino & Raspberry pi as well.
