8 Channel 5V Relay Module
This is a simple 8 channel relay module. It can be used to control lighting, actuators and other electronic equipment. It's great for use with an Arduino and most common microcontrollers in a system where higher voltage control is needed. The Relay output state is clearly shown by a light-emitting diode at the base of the board.
