Interesting design -- lots going on.

What's the 4-pin header on the top of the board? I can't quite read the silkscreening.

Are the various blue daughterboards also your design or third party?

And did you mention the rating of those little relays? Both coil switching voltage/current and max. load ratings for current @ VAC & VDC?
