From the project

Orientation paddle PCB for NSSL EFM

In the paddle opposite the motor driver, an orientation sensor based on a simple IMU provides rough data on the instrument’s orientation over time. This allows analysis of pendulum motion and other movements of the full instrument package. The system is designed for easy sensor replacement, and all orientation data are logged to a microSD card.

See the main instrument repo for documentation and the rest of the instrument.
