This module is made to drive 8 independent relays with an Arduino Nano. Its power supply unit is for 120 and 220VAC, to power the relays and the Arduino Nano. The relays can be triggered by setting the pin from Arduino Nano 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 Nano with ATMeaga168 included.
