Software

The software repo is here. The board is programmed using Platform IO in VS code.

Setup instructions assume board is just being used for data logging (TODO: add instructions to use as flight computer)

Ensure the board is not contact any metal surfaces
Check that the internal power header pins aren't connected (see photo)
Insert SD card into Teensy
Connect the Teensy to a computer via USB
Upload firmware using Platform IO
Data should be logging, and serial data being sent to the computer. Open the Serial monitor to check that everything is working.
Unplug the teensy from the computer. Verify the SD card has data written to it by plugging it into a computer and opening the file.
Put the SD card back into the Teensy (it's okay to leave the program, a new program file is created every time it is turned on)
Insert the internal power header jumper cap to have the Teensy powered by the battery
Screw a connector into the power in port
Verify polarity! Red on top, GND on bottom
(Optionally) add any arming circuitry to the power port connector, such as a magswitch or toggle switch
Plug the battery in and turn on. Unplug immediately if the light does not turn on and buzzer doesn't beep
Teensy should be in fully operational data logging state. It will have slow chirps indicating that it's logging data, and a green flashing LED. Fast beeps and a red LED indicate an error. If that happens, unplug, remove the internal power header jumper cap, and plug in with USB to view serial data.

Packing list:

Integration:

Battery fully charged (around 8.4v)
SD card has sufficient capacity (Data logs generate about 10 megabytes per hour)
SD installed into the slot and retained with tape
Internal power jumper installed (top right)
Board powered on, displays green LED and correct chips, and then powered off again
