# 6/30 avionics design review

## criterias
- compatability
- active fin stabilization/TVC built in
- modularity
- independent power unit
- independent sensor suite
- independent flight computer
- other modules
- expandability
- use standard pins to connect each other
- can provide 3.3,5,12v with 5A total

## flight profile
- future proofing
- current mission
- 1KM
- would encounter water(air tight)
- less than 16G accel
- no active control
- nice to haves
- recover avionics stack
- recover footage

## design ideas
- modules
- 2 x connected with 2.54 2x10 pins
- female at top male at bottom
- x+ power x- signals
- debugging uart/I2C/SPI
- first design should use breakout board

**first prority**
- design flight computer and sensor suite

**laters**
- design dedicated power distribution unit

- module specifics
- flight computer stack
- Teensy 4.0
- gravity logger
- communication RFM95
- switching stack
- fin servo pins
- tvc servo pins
- pyrotechnic MOSFET
- parachute
- ignitor
- seperator?
- Power Swithcing
- camera
- sensor suite stack
- IMU MPU950
- barometer BME280
- humitider DHT22
- thermocouple MAX31855
- power INA226*3(3 voltages)
- power stack
- LiPo battery
- PMIC protection
- reverse polarity
- short circuit
- low voltage
- voltage distributing
- arming pin(physically)
