Note: It is possible to use this board with Raspberry Pi and other 3.3V boards, but you will need to provide 5V for the relay coils and remove the 0ohm resistor shown below:


Note: The schematic above includes the version board with 12V relays and step-down power supply for 5V. The version we are selling doesn't have the step-down power supply and have 5V coil relays.
