Per Compex's datasheet...

  • "C-432JPW 7A03" is silkscreened on the board shown
  • It seems to be indicated that there are (or will be) two item codes for the device..
one for a low voltage (12-24V PoE) and one for a high voltage model (36-48V PoE)
DC jack input is noted as 12-24V for both boards
  • CompexWRT is noted as the stock OS - it seems to be derived from OpenWrt
  • OpenWrt is (or will be, if not now) supported on these boards
