- 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
