Overview

The FCC ID covers the daughterboard for the unit.
The daughterboard is a Cameo product and it is assumed the main board is also OEM Cameo.
There is a Pericom packet switch on the wireless module board, same as the D-Link DIR-827.

Reviews

This device appears to share the same basic hardware as the D-Link DIR-827.

The main elements of the other board are placed on one side. A Ubicom IP8000AU chip is used as a SoC processor.
RAM is represented by two 256 Mbytes NANYA NT5CB128M16BP modules meaning that the overall RAM available to the device is 512 Mbytes.
One of them performs the sole function of a wireless module and uses a PCI-E Pericom PI7C9X20303SL switch.
