Peripherals

2.15

System FAN connector (SYSFAN1)

If fan is used, this connector supports cooling fans of 500 mA (6 W) or less.

2.16

AT power connector (PWR1)

If you prefer not to acquire power through the PCA-6742 backplane via the gold H-
connectors, the big 4P power connector (PWR1) also provides power input connec-
tors for +5 V, and +12 V.

2.17

GPIO Header (GPIO1)

Provides 14-Pins pin header for Digital I/O usage. Refer to Appendix B for detailed
information on the pin assignments and programming guide in Appendix C.
The board supports 8-bit GPIO through GPIO connector. The 8 digital in- and out-
puts can be programmed to read or control devices, with input or out- put defined.
This GPIO is CMOS level (0 ~ 3.3 V).

2.18

Flat Panel display connector (LCD1 & LVDS1)

PCA-6742 is capable of driving flat panel displays.

2.18.1

TTL TFT LCD connector (LCD1)

For PCM-6742, LCD1 consists of a 40-pin connector which can support 1024x768 @
18/24-bit TTL TFT LCD panel.

2.18.2

LVDS TFT LCD connector (LVDS1) (Optional)

For PCM-6742, LVDS1 consists of a 20-pin connector which can support 1024x768
@ 18/24-bit LVDS TFT LCD panel for optional.

2.19

PC/104 connector (PC104)

The PCA-6742 is equipped with a 8/16 bit ISA signal PC/104 connector for future
expansion.
