Preliminary 8
Jumpers J1 and J2 are used to select the 3.3V (J2) and 5V (J1) power sources for the Evaluation board.
Jumpering 1-2 selects power directly from the bus while 2-3 selects power from the regulators on the
adapter that receive their power from the AC adapter used by the platform.
Lubbock Platform
The Lubbock platform has a single 140-pin connector, J26 that interfaces to the adapter board (described
earlier) that re-routes several signals necessary to work with the Evaluation board. The final assembly
should resemble the diagram below which is a side view of the Lubbock platform and Evaluation Board.

PXA2x0 Adapter Board
PXA2X0 (Lubbock) Platform
The MQ1168 peripherals with the exception of the flatpanel interface need to signal the PXA2x0 on the
Lubbock platform with an interrupt. Our device drivers have been ported to use GPIO 10/RTC on the
Lubbock connector as the interrupt pin. GPIO 10 comes out on connector J21 pin 3 as defined in the
Lubbock user guide on page 2-13. If you intend to use GPIO 10 you need to solder a wire from the
MQ1168 interface card connector U2 pin 108 to Connector J21 pin 3. Other interrupt pins can be used by
connecting them to Pin 108 of connector U2 on the interface card, however the drivers will need to be
modified.
Assabet Platform
The diagram below shows how the Evaluation board, adapter board and Assabet platform are connected.
Care should be taken to line up the pins correctly, especially A1/B1/C1. Also, when removing the adapter
from the Assabet platform, care should be taken to ensure the boards come apart as parallel as possible or
the pins on the male adapter board connector can be bent or the plastic shroud broken.
