"2050500289" and "Rev:1.0" is silkscreened on the board.

• CPU: Freescale Semiconductor QorIQ P1014 (@800MHz)

Hardware NAT acceleration w/ Atheros AR8327N switch

(.. but not currently, or likely anytime soon, with OpenWrt)

Links

• On the OpenWrt forums (OpenWrt boot log posted by Gabor Juhos)

Freescale P1014 @800MHz (P1014RDB board), 128MB DRAM,

168c:abcd (hm.) and 168c:0033 (AR9580) PCI IDs

• On the OpenWrt wiki

There would appear to be two versions of the device..

• v1 - worldwide version, Freescale based
  • F8:1A:67 OUI, per the censored label
  • changeset (r36051) adding profile build image for the device
• v2 - China only, QCA QCA9558 based
  • v2 on the OpenWrt forums

• Review on redeszone.net (ES) (w/ excellent internal photos)

De-heatsinkized CPU visible as a Freescale P1014NSN5HFA (P1014)

- not a P1010.. but there does not appear to be anything significantly

different between the two models P1010 appears to have 3x GbE SGMII

(vs. P1014's 2x) and trusted boot support

WiFi chips visible in their photos as AR9580 (AR9580-AR1A) and AR9381

USB 2.0 hub (P1014 has only 1x USB 2.0) is a Genesys Logic GL850G.

• Review on uk.hardware.info

specifies WiFi chips as AR9385 (no) and AR9381
