1. Models and Attentions
1.1 Models
This manual is applied to flowing models:
1.2 Attentions
1) Notes under a table or figure indicate the difference of models, or alternative definition of specific pin
of the header (jumper/connector).
2) How to identify the first pin of a header or jumper
Usually, there is a thick line or a triangle near the header’s or jumper’s pin 1.
Square pad, which you can find on the back of the motherboard, is usually used for pin 1.

Notes:
[1]: CPU can be customized into Intel®AtomTM D2500、N2800、N2600.
[2]: The dual channel 24-bit LVDS supports a max resolution of 1920x1200, and it can be changed to a
single channel 24-bit LVDS with a max resolution of 1440x900.
[3]: The HDMI and RJ11 Connectors on rear I/O share the same position and are mutually exclusive.
[4]: SATA1 supports SATA DOM (need corresponding hardware supported).
[5]: LAN can be customized into Single LAN or 100Mbps LAN.
[6]: Mini PCI-E1 and SATA2 share the same SATA signal, they can’t be accessed simultaneously.
