From the project
Artisanally hand-crafted bespoke backplane for OreSat.
The OreSat CubeSat bus uses a card cage / backplane system based on a 1 Mbps Controller Area Network (CAN) bus and a 2 cell Lithium ion battery power bus (6.0 - 8.4 V). There are ~ 8 cards per CubeSat "U", and the board is meant to be general purpose enough to allow for some card swapping. The RF lines, however, are microstrips on the backplane PCB so the backplane must be rev'd for changes in the RF cards. There are three sets of connectors:
