  1. Looking to get a Sainsmart relay board to help my Pi control my garage door opener via GPIO pins. Can anyone tell me what the difference between a 2-channel and 4-channel relay is? I would assume that I would be able to get away with just a 2 channel for this application? p.s. Should mention that I will also incorporate magnetic switch to check the state of the garage door as well. Thanks!
