Google Fiber Network Box

Support page
Open source and GPL code for the device (on Google Code)

Per the source, this device is using 88F6560 (AVANTA family) with 88W8764 radios.

The firmware is OpenRG based. .. the device seems to be quite similar
to the Actiontec MI424WR rev I‎, which is also referenced in the source..
and thus likely uses an OpenRG based firmware as well (but I don't feel
like downloading it to confirm this ATM), UBoot bootloader, NAND flash

The main board is silkscreened with "Actiontec" and "06694A" in the FCC photos.

There is a Marvell GbE Switch / PHY on the board. The SoC is covered by a heatsink.
As the SoC is AVANTA based, the device is likely using the internal SoC switch core..
These screen shots show that the device is most likely made by Actiontec for Google.
Per the system information, Platform: Actiontec Rev-K Board
MACs have been fully censored from Web UI screenshots
This revision appears to have a Fiber interface (w/ a NeoPhotonics module per
the FCC images), though this appears to be omitted on production models.

Other Notes[edit]

Appears to have same 1x6 pin 3.3v 115200 baud UART connector as GFRG100.
