Think about connectors

Backplane Connector Decision

  • 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 




Goals by start of AY 2022-23

  • Connector(s) selected
  • Protocol selected
  • Voltages selected
  • Good idea for sensors
  • Good idea for module breakdown
  • Microcontroller selected
  • Requirements enumerated
