FPV Head Tracker for ExpressLRS Radios

This project is a DIY wireless head tracker for FPV drones and RC vehicles. It uses an ESP32-C3 Super Mini and a BNO085 IMU to convert head movements into PPM trainer signals, allowing you to control pitch, roll, and yaw through the trainer port of an ExpressLRS radio.

The enclosure is designed for easy assembly with screw-mounted electronics and includes a rechargeable Li-ion battery, USB charging, battery voltage monitoring, an audible low-battery buzzer, and interchangeable bottom covers for use as either a head tracker or a handheld motion controller.

The complete project—including source code, schematics, and build instructions—is available on GitHub.
