From the project

New public repo for work on LED Glasses

The hardware consists entirely of three PCBs without an enclosure with low profile hinges and a battery system that has yet to be worked out. The PCBs are designed in KiCAD and are as follows:

- The controller arm (hardware/armmcu) which houses the microcontroller (STM32G071KBU6), a microphone (SPH0641LM4H-1) and a 3v3 linear regulator. - The power arm (hardware/armpower) which houses input power protection, an on switch, 5v5 switching regulator and a power good indicator. - The front display (hardware/frontdisplay) which houses the LED matrix (SK6812MINI`).
