In addition to the previous board, we are also developing an alternative control method.

This self-contained module is based on the nRF51822 Bluetooth Low Energy SoC and a BNO055 IMU with on-board sensor fusion, and is powered by a CR2032 battery cell.

The idea behind this board is to provide an alternative to people who may be unable to use the joystick, and could control the chair using head gestures along with a dis/enable position to avoid sending commands involuntarily.
