[Idea] USB cradle and rechargable.

[bademux]

Hi,
It will be nice to have cradle for SW, we have 4 external contacts for plastic cases:
3 metal buttons (please see images) + backplate. Backplate can be mounted upside down to expose GND.
Basically we have USB without a case modification.

It will be great to implement charging.
Have wired connection to board without case modification.

I see some problems:
if board is connected to USB and battery present, then battery will h
ave current on its contacts. Maybe supercapasitor can be used?
I'm not sure about static electricity.

note:
photos represent kind of PoC: cooper adhesive tape is too soft for daily use.

Great idea! 💡

The other approach could be to make a custom CNC back with a NFC chip that could be used both to load the device and to transfert data from and to the device.
