From the project
PiFire Solid State Relay Module PCB
This PCB is designed to support mechanical relays for controlling incoming Power(L) to the Igniter, Auger, and AC Fan. This board uses compact solid state relays that are able to handle high power. This is an alternative to using an off the shelf relay module which simplifies the wiring and even allows you to use the OEM harness.
The design intent for this board was to make a DIY accessible PCB that can be more easily put together by the maker/enthusiast of almost any skill level. Full size components are used in most cases and most (if not all) parts should be readily available to order…
