Unit is ultrasonically welded - I first carefully worked a razor knife around the edge, but that wasn’t enough. I had to use a couple of small jewelers screwdrivers to get the back to separate the back. Be careful, the main PCB spans the entire back, and is only 1/4”” away from the back cover. The microcontroller is on the small PCB attached to the front panel with 2 screws.

There are clearly marked pads for 3v3, GND, TX, RX, GI0.
