I've been slowly building/researching a raspberry pi based brewery controller (3vessel eHERMS), and plan to use crafteerpi to run it... I've seen it mentioned in a few places that the expansion boards etc are necessary in order to not fry components... but on the craftbeerpi.com site, there's a wiring diagram that shows SSR's connected directly to the Pi GPIOs. I already have 40a SSR's that can take 3v input, contactors, switches, etc. just need to wire it up... any reason to NOT forge forward with this build as planned?
Or am I not understanding the difference and the terregady boards have a different purpose?
