Overview

The Ubiquiti Networks logo and "SIMPLE AP N" appears to be silkscreened on these boards.

"11-00124-04" and "UBIQUITI NETWORKS (C) 2010" is also etched onto the board.

The wireless chip used is apparently the AR9285 [1] [2].

There are U.FL connectors on the board, but they are not connected by default.

UBNT's FCC internal photos for this device are perma-confidential.
