Apogee Avionics

Long Term/Break Goals

  • Design PCB

  • Research/select components all but servo which is reliant on test platform (Accelerometer/IMU, Barometer, Microcontroller, maybe storage)

  • Learn more about zephyr, talk to other team members Richie Sommers and big avi people (I don’t know specific names my b - Jackson)

  • Be cool and awesome do great things be smart and safe

 

design requirements:

Microprocessor for running simulations and deploying airbrakes
Servo with sufficient power to control airbrakes
Read data from IMU, altimeter, and sensor mod
Store data to flash
STM32 chip
Figure out if we can get enough current
Ability to do RS485
ADC for load cell
LC filter
power from backplane
Ethernet interface
run a test on a L2 rocket
silkscreen of a smiley face
Minecraft font on PCB (NO COMIC SANS)

 

L2 test design requirements:

test basic functionality of air brakes
create a power supply capable of emulating power mod
implement design into an L2 with single event reco

 

Things we need to know

peak current draw of servos
how long will the servos be running
weight requirements

 

RS485 candidates:

Link 1
