We have just received all the components and bare PCBs for the chair.
Until now we've been using a Nucleo board and a step-down regulator in the control panel. While this works, we wanted to go an extra step to get rid of the mess of cables. The new board handles communications through a CAT5 cable and can take in the 14V provided by the hoverboard. We have also added BLE 4.0 connectivity through an nRF8001 chip to open the chair even more to mobile apps or alternative control methods, such as gesture or eye-gaze based.
