Overview[edit]

Note: This model is not the VR900, but the VR900v. Both differ quite substancially in both hardware and pricing. Be careful not to mix up "VR900v (v1.0)" and "VR900 (v1.0)"!

Notes[edit]

Specifications[edit]

The device runs on 2 entirely different SoCs:

CPU:

  • Broadcom BCM4709 (2x 1GHz ARM Cortex-A9) with RAM 128MB and flash 16MB.
  • Broadcom BCM63168 (2x 400MHz MIPS) with RAM 64MB and flash 8MB.

Flash:

Spansion S25FL128SAGMFI00 16MB (FL128SAIF00, 439QQ0009 A, SPANSION)
Winbond W25Q64FVSSIG 8MB (Winbind, 25Q64FVSIG, 1532)
Winbond W25Q80BVSSIG 1MB (Winbond, 25Q80BVSIG, 1444) (DECT)

RAM:

SK hynix H5TQ1G63EFR-PBC 128MB (H5TQ1G63EFR, PBC 444V, NWLC2479XH3)
Zentel A3R12E40CBF-8E 64MB (A3R12E40CBF, -8E, 527ZENV6, 57025694G-F)
  • For wired ethernet connectivity, the integrated NICs of the BCM4709 are used.
That SoC supposedly also features some hardware offloading capabilities
as well as hardware accelerated routing.
  • Wi-fi is provided by 2 BCM4360 with an unknown number of antennas.
The device has 3 external RP-SMA connectors for wifi, yet the exact
wiring/mapping is unknown.
(root@localhost.localdomain) (gcc version 4.6.2 (Buildroot 2011.11)) 
#1 SMP PREEMPT Mon Aug 24 10:08:45 HKT 2015;unknown OS on BCM4709

Serial[edit]

The device has at least 2, possibly 3 serial interfaces

on the unpopulated 4 pin headers J4, J7 and J8.
  • J4 (unpopulated 3.3V TTL, RX-TX-GND-VCC, 115200,8,N,1)
  • J7 (unpopulated, 3.3V TTL, ?-?-GND-VCC)
  • J8 (unpopulated, 3.3V TTL, RX-TX-GND-VCC, 115200,8,N,1)
All operate at 3.3V TTL, J4 and J8 run at 115200,8,N,1,
whilst the exact function of J7 is yet unknown.
The pinout of all headers is RX-TX-GND-VCC, whilst the exact
function of the RX and TX pins on J7 is yet to be found.
At least on my board, it was virtually impossible to solder the GND pins
on all 3 headers (the other pins could be soldered without any problem).
You probably need to brass-brush them prior to soldering (do not brush
them after soldering or you will spread fine-ground solder over the PCB,
causing possible shortages!).

VoIP / DECT[edit]

  • 2 separate VoIP ports are offered through which POTS telephones can be used for VoIP
telephony. Both ports feature a German TAE socket and a classical RJ11 socket.
I have not tested if you can connect 2 phones simultanously to the same VoIP port.
  • DECT is provided by a DSP DCX81 with a small separated antenna PCB which is integrated
into the router's plastic case and is not visible or accessible from the outside.
