Others
Compex is marketing this device as an 802.11ac ready device - it is designed to be accompanied with a large form-factor Mini PCIe 11ac radio (like the WLE900N5 or WLE900N5-23), though all WLE series radios are noted as being supported.

The datasheet provided by Compex states there are two item codes for the board... Additional information, per the datasheet, follows...
 * WPJ344LV 6A03PC8128BR - LV (low-voltage - 24 VDC) variant
 * 9 to 24 VDC via DC jack, 12 to 24 VDC through PoE
 * WPJ344HV-A 6A09PO16FBRBP - HV (high-voltage - 48 VDC) variant
 * 24 to 48 VDC via DC jack, 24 to 48 VDC through PoE
 * "C-344JPW 6A02" is appears to be silkscreened on the board.
 * Power consumption (board only): 5 W
 * Dimensions: Dimensions::117 mm x 105 mm x 17 mm
 * FCC & CE Certified, REACH and RoHS Compliance
 * A USB extension board (w/ 2x Female A and 1x USB-only Mini PCIe) is (optionally) available

"C-344JPW 6A01" is silkscreened on the board pictured in the prelimary datasheet.
