OpenEarable open source in-ear wireless headphones (finished version)

OpenEarable aims to enable ear-based sensing applications by providing a flexible open source hardware platform. It integrates a range of sensors, including a 9-axis inertial measurement unit, ear canal pressure and temperature sensors, inward-facing ultrasound microphone, speakers, buttons and controllable RGB LEDs. With these capabilities, OpenEarable provides researchers and developers with the ability to explore a variety of application scenarios.

OpenEarable controls and transmits sensor data via BLE (Bluetooth Low Energy). Audio is played from or recorded to the internal SD card. OpenEarable is compatible with the provided dashboard and Edge-ml.
