Meru Networks AP320

"MERU TRISULI DVT2.0" is silkscreened on the board.

This device is using a...
 * Freescale Semiconductor MPC8347 ("MPC8347EVVAJFB", "533/333MHz", "QMZNL0738", "MALAYSIA")
 * and alternately, SK hynix HY5PS121621C FP-Y5 RAM, and Spansion S29GL128P90TFIR2 Flash

This AP (and other Meru Networks APs) are designed to be used with a centralized AP controller.

Pinout
It seems likely to be the following.. J2 [3.3] (RxD) (TxD) (GND)
