Serial

Pinout

It's on the back of the unit, presumably.

Tx seems to be the large used pad next to the two large grounded pads - both of which are somewhat below the power connector. The output doesn't appear to be particularly useful.. a trait which may be shared with other Global Sun AR231x + ThreadX devices..

Probable used PSU(s)

The power supply which seems to be bundled with US sold units looks to be a JENTEC JTA0302A. The connector is smaller than usual..
