Appendix B: Connector Pinouts
The QVGA Controller comprises a stack of three boards: a display backplane, the QVGA Board, and the smaller QED-4-QVGA Board (aka QED-Flash Board). Pin-outs for all I/O connectors on the QED-Flash Board or the QVGA Board are provided here.
Warning – Do Not Connect to System Control Signals
When connecting to the Digital I/O Connector (H2 on the QVGA Board) with a ribbon cable, notch out cable wires 11 through 24. Even short pieces of wire connected to some of these lines may cause intermittent operation of the touchscreen or processor.
When connecting to the Supplemental I/O Connector (H3 on the QED Board) with a ribbon cable, only connect the wires you need, and do not connect to the data bus lines or system control lines.
QED Flash Board Connectors
The pinouts of all of the connectors on the QED–Flash Board are presented below. To locate the connectors on the board, consult Figure B–1 and the white silk–screened labels on the visible side of the QED–Flash Board. The arrows in the figure point to the locations of pin 1 on each connector.
QED–Flash Board Connectors and Switches. Arrows locate pin 1 of each connector.
