What's the connector and interface for the side units? They slide on and latch, so no common connector will work.

I think they're all Bluetooth, and the slide/latching is purely for human interface, not digital. :)

The side units charge while attached, if the main unit has power, so there's some connection.

Oh, I didn't think of that. Good question indeed.
