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

Register Bits

Dump in a register value and get a binary representation that makes decoding registers just that bit easier.
