This single channel Relay Module is specially designed for low-voltage devices and works well with 3.3V power supply. It can be used to control the lighting, electrical and other equipments through the digital IO port. The module comes with on-board back EMF protection to eliminate the voltage spikes and surges.
The mechanical contact of this relay module is able to handle up to 10A current. An on-board indicator LED demonstrates the relay's state. The module is controlled with 3V signal and they are pre-soldered. A logic "LOW" to the control pin will activate the relay.
