GPIO Raspberry PI


Active Member
I found some threads about people building GPIO boards, on another forums, for their raspberry pi's and use MQTT to provide state status for home assistant.  I am looking to expand those boards - just because and really the omnipro isn't gonna last forever. 
I Have some questions. Is anyone interested in this? 
I never used the outputs on my Omnipro for anything OTHER than Relays.  Is there a good reason NOT to integrate a relay for the outputs on said board?
Let me know if you guys have any other ideas for specifications for this board.
I am trying to find the removable terminal strips that HAI used, but it seems to be the holy grail.  I was thinking of some spring loaded jobs? Thoughts on this?
