Implementation

~~Battery level on feather neopixel (green = >80% ; yellow >=40% ; orange >= 25% ; red < 25%)~~
- ~~https://learn.adafruit.com/adafruit-feather-m0-basic-proto/power-management~~
Setup 2nd feather + proto board as a 40 pin socket
2nd feather acts as a mux between different rpi uarts (0 and 1 and 5 in particular)
2nd feather talks via qwiic connector over i2c to main board
User button on feather to flip between usb and local serial (aka : can be used as a serial adapter)
- Note this on the UI
Fall back to internal uart pins if no expander is present
- Note this on the UI
Main board startup shows connection setup + waits for OK prompt via main hat switch
Main board has a status bar @ bottom with battery level, selected uart, selected speed
Main board does simple display of serial in/out via lcd
Main board has a button for accessing symbols via pop-up list that aren't on keyboard
Main board has a button for accessing a uart selection pop-up that maps to rpi uarts
Main board has a button for accessing password selection pop-up to help with password entry over serial
Main board has a button for accessing uart speed pop-up to help with configuring line speeds

Closing / wontfix as this is well outside the scope of PiFrame. Moved to a personal project instead.
