- USB hub that can do power control on one port (via pico), one USB-A female port for going to the phone
- second USB goes to pico
- 12v in via a barrel jack which powers an LDO with ~3.8-9v 4A output
- output adjustable via software or just a pot
- output voltage/current measured by MCU
- Pico attached to board
- pico GPIO pins exposed via some header for phone UART and button control
- Should have a jumper to adjust between 1.8/3.3v UART
- (just 1.8/3.3v is fine and i know from experience that a single voltage divider on the TX is enough for this)
- Spare i2c and a few extra GPIOs for future expansion
