Booting the thing
Todo / Open issues
- Have not yet connected the old USB ports / Ethernetport. Have to make room for a USB hub
- Add second Lithium Cell
- Need to connect the speakers to the audio out on the lcd driver board.
- Charging USB-C is working but need to switch of the RPI casue the power drops too low.
- Also when USB-C is connected the powerbank IC shuts the power for a short time.
- Will add some capacitor/batttery to survive a charge cable connect
- Micro SD extender is glitchy not reliable.
