This module is made to drive 8 independent relays with an Arduino Pro Mini. Its power supply unit is for 120 and 220VAC, to power the relays and the Arduino Pro Mini. The relays can be triggered by setting the pin from Arduino Pro Mini to HIGH. Also, on the relay shield is an I2C bridge, with the MCP23008 connected to ULN2803, so You can also use the I2C protocol to drive the relays.
The price is the Arduino Pro Mini with ATMeaga328p included.
