Backplane Meeting - 9/14/22

Backplane

• 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

Power Module

• 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

Autopilot Module

• Ben not here

• Idea: add ability for servo control

Sensor Module

• Sensors selected

  • This rocket might exceed 20g

  • 56 mg resolution on high-g is not that bad

• Starting schematic capture

Radio Module

• Currently planning on using an XBee (not pro due to availability)

• Pushing power until after link budget is satisfied

Flight Computer Name?
