Think about connectors

Backplane Connector Decision

• Quantify what we are looking for in a connector
• Connector possibilities:

  • https://www.molex.com/molex/products/group/board_to_board_connectors
  • https://www.te.com/usa-en/products/connectors/pcb-connectors/board-to-board-connectors.htmlhtm

• Breakout I/O from each module through backplane instead of having individual breakouts on each module
  • Each backplane port has a unique pair of GPIO pins sent to e.g. a DE-25
  • All GPIO in one place for ease of integration
  • Less of a rats nest of wires in the av bay

Connector Limits:

12 pins at 3A

24 pins at 1A

+6 power wires (VBat, 5v, 3.3v, GND, GND, GND)

+ 4 Ethernet
