Backplane Meeting - 9/14/22

• SwitchBlox microswitch going forward
• Connector not selected until specific power/IO
• Added GPIO block to diagram
• found memo that says no need for magnetics?
  • one reason for magnetics is to support high current + high voltage AC through any port (part of IEEE 802.3)
• Everyone get maximum GPIO pin count they need so we can decide on a module ↔ backplane connector
  • Probably driven by autopilot
• Power req not sent
• Every module sends a heartbeat to GPIO for blinky blinky

• James not here
• Updates made to block diagram / other comments from last meeting
• Still need power, voltage, & current requirements from each module and the backplane

• Ben not here
• Idea: add ability for servo control

• Sensors selected
  • This rocket might exceed 20g
  • 56 mg resolution on high-g is not that bad
• Starting schematic capture

• Currently planning on using an XBee (not pro due to availability)
• Pushing power until after link budget is satisfied
