Altium License RenewalWill be reaching out this week about it

Components Selection TrainingJim Heaney Running training after next general?

Backplane

  • Radio
  • Power
  • Backplane
  • Sensor
  • Autopilot 
  • Radio
    • Basic block diagram needs to be checked
    • APRS? 
  • Power
    • Block diagram finished needs to be checked
      • Add 7.4V to backplane
      • Add Wiznet chip
      • Add umbilical
      • might switch to two buck/LDO pairs based on current/voltage of other modules
      • Add 2nd battery input w/ some sort of switching capability
      • Add test port (SWD over JTAG connector)
      • Add status LEDs
    • need max current and off which voltage rails from other mods
    • Switcher w/ integrated inductors justification:
      • Lower EMI (usually meet some standard)
      • Simplifies component selection/design (1 IC vs 1 IC & a bunch of passives)
      • Relatively small cost add compared to design simplification
      • No/little to no need to add shielding to module
  • Backplane
    • Block diagram is finished needs to be checked
    • Might not need magnetics cuz if having all the mods sharing ground it doesn't do anything. But no reason not to have them if have the space?
  • Sensor
    •  Block diagram finished needs to be checked
  • Autopilot
    • finish block diagram
      • currently need beefy micro controller
        • STMF4 at least cuz f0 is not powerful enough for good state estimation
  • Other
    • Arming will be easy access somewhere on rocket tbd later
    • not micro sd for storage 
    • Whoever picks a micro controller first selects it 
      • STM32 is preferred - makes software easier
