Construction

Tradeoffs of connector types

Board-to-board: pin current ratings are just what you need (+), more flexible inter-PCB spacing (+), pin out only those signals that you use (+), totally custom boards (-), only one assembly sequence / layout (-), rigid / no wiping (-)

Board stacking: typically large inter-board spacing (+/-), all pins (even unused ones) carried through (-), more general, more standard (+), pins all high-current (excess capacity) (-), arbitrary assembly sequence (+), wiping action (+)

Boards can be interconnected via

Unique point-to-point / board-to-board topology (e.g. CP series)

“Backplane” topology (e.g. GeneSat – dedicated slots)

Stacking approach (e.g. CubeSat Kit)
