Components Selection Training

Running training after next general?

Backplane

@backplane owners

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

Autopilot
