Description
Skydiving Altimeter built using a TENSTAR TS-ESP32-S3 board, and a 1000MA battery.
DO NOT USE THIS DEVICE AS YOUR PRIMARY ALTIMETER.
This software and hardware design is for educational and hobbyist purposes only. It has not been tested against industry safety standards. Electronics can fail, batteries can die, and code can crash.
ALWAYS jump with a multiple redundant system of industry standard, commercially manufactured audible and visual altimeters.

IMPORTANT: The polarity of this battery as shipped is backwards from how the board's connector is wired and will fry the board. You have to swap the pins in the connector in order for it to work correctly.
