Overview

"45-401-000503" is silkscreened on the board (Rev1).
"45-401-000681" is silkscreened on the board (Rev2).

There are (at least) two versions of the board:

Rev1: the WIFI module is connected to a mini-PCI slot, with TI chips.
Rev2: the WIFI module is integrated into the main PCB, with Infineon chips.

Note: The Infineon (Lantiq) PSB7200ZDW SoC is also known as TI AR7

TNETD7200GDU. Infineon (Lantiq) PSB1350A aka TI TNETW1350A.

The ZyXEL P-660HW-D1 was an ADSL2+ wireless router widely

distributed by some ISPs like Telefónica (white enclosure).

The PSU adapters used by the ZyXEL original (black enclosure) and

the one distributed by Telefónica (white enclosure) are different:

ZyXEL (black enclosure): 12V AC 1A
Telefónica (white enclosure): 16V AC 1A

If you wanted to use a PSU with lower voltages than the original,

then a modification at the circuit with the voltage comparator IC (AS/LM393) should

be done, otherwise the CPU will keep in a reset state avoiding too boot the system.

Desoldering the R177 resistor near the LM393 IC should work.

This way the R114 pullup resistor connected to the 74LV08 AND gate will (via another

AND gate) permanently pull the CPU and memory flash chip out of reset.
