The device runs OpenWrt on the stock firmware.

The power supply voltage range is 12VDC to 24VDC.

"081R-MPB880AN00 R06" is printed on a sticker attached to the bottom of the unit.

This would seem to indicate the device was manufactured by U-MEDIA.
"Designed in U.S.A." is silkscreened on the top of the board.

Note: The PCI controller on 7161 cannot handle I/O resources.

This isn't a problem for Atheros based Wi-Fi cards, but it is generally a problem for others..
