'''TODO ADD PHOTOS OF THE BOARD'''

Right from the start the board offers several unpopulated pinheaders for JTAG and SERIAL. A quick check with the Oscilloscope reveals the pinout. And a logic analyser tells us the required baud settings. Baudrate: 115200 8N1 of course no hardware flow control. The voltage levels are 3.3 volts.
 
The core of the board is a '''ATMEL AT91SAM9620'''.
The board contains the following ICs
 
RAM: 48LC16M16A2 - 256 Mbit
 
FLASH: 29F2G08ABAEA - 2Gb 16bit blocks
 
CPU: ATMEL AT91SAM9620
 
Ethernet tranceiver: KSZ8041NL
 
ZigBee Module: ETRX357
 
The rest is voltage regulation and logic
 
 
Here is the boot chatter of the bridge.
The system is a AT91SAM9G20 at a clockspeed of 396 MHz running Linux with a kernel version of 2.6.36.4 in April of 2013
It has access to 32 MegsMB of RAM and 256 MiB of Flash (far moreless than requiredis availible but still great for the purpose).
The boot process finishes in a login prompt.
The obvious passwords default passwords don't work.
