The piggybacked board is a Duex5.
I'm particularly interested in if there'd be any signal problems with the ribbon cable folded between the boards.
There's Kapton tape protecting the cable physically and I could easily shield it with copper foil if needed.
Oh yeah... The bed mosfet on the main board will only be driving SSRs and the mosfets on the Duex5 aren't going to be used so no heat issues there.
Thoughts?
