Specications
Mechanical and Enviromental
Size/Weight:
185 mm x 122 mm (7.3” x 4.8”), 0.27 Kg (0.59 lb)
Power Supply Voltage: +5 V, +12 V, ±5%
Power requirements:
- Max:
2.26 A @ 5 V, 0.5 A@12 V
- Typical:
1.22 A @ 5 V (w/Celeron M 1 G + 256 MB RAM)
0.01 A @ 12 V (w/Celeron M 1 G + 256 MB RAM)
Environment: 0 ~ 60°C (32 ~ 140°F), operation
Operating Humidity: 0%~90% relative humidity, noncon-
densing
Note: If your PSU doesn’t have +12 V output (+5 V
only), PCA-6781 needs to go T-part number to
add the components for the 5 V to 12V convert-
ing circuit, but LVDS and PC104 also cannot be
used within +5 V only.
Jumpers and Connectors
Connectors on the board link it to external devices, such as
hard disk drives, a keyboard or expansion bus connectors.
In addtion, the board has a number of jumpers that allow
you to configure your system to suit your application.
