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..

JENTEC JTA0302A (more)
Input: 100-120 VAC ~ 50-60 Hz, 0.5 A
Input connector: NEMA 1-15P Style: small, straight
Output: 5 VDC, 2 A
Output connector: barrel (center +)  OD: ??  ID: ??  LEN: ??

JTAG-Serial Info

Serial

Serial Pinouts

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..
