Relay Driver Shield

An Arduino shield for controlling four 12v relays. The schematic and PCB layout were created using KiCad.

While it is designed for relays, it can be used for powering anything that requires a bit more current or voltage.

Arduino Pin	Function
D5	Relay 1
D6	Relay 2
D7	Relay 3
D8	Relay 4

The output voltage is determined by the input voltage on the Arduino Board - the VIN pin.
