JMCPU - PCB001: Backplane


Backplane PCB to link other PCB together. Each PCB interconnects up to 6 cards and allows daisy chaining thanks to angled connectors on the edge.

3 backplane cards are required for daughter boards with 3 headers, 2 backplane cards for daughter boards with 2 headers.

Mounting holes have a regular spacing even across multiple chained cards. A daughter card can be plugged horizontally on the left female angled connector. The whole backplane assembly can be plugged as a daughter board on another set of backplane cards.

Daughter boards should be held together using 11mm spacers.
