4.1 J1, DC Input Jack
The 2.1mm DC Power Jack should be used for connecting a small wall mount unregulated power adapter,
supplying 9V-12V DC at 10 VA, with a 5.5mm outside, 2.1mm inside female power plug with plus at
center pin. It is protected against reverse polarity.
4.2 J2, 3.3V PCI Connector
PCI rev 2.2 connector, please see the PCI Specification rev 2.2 for pin layout and electrical specifications.
Also, please see the “Bus Expansion” section for limitations.
4.3 J3, Mini-PCI Socket
Mini-PCI type IIIA socket, please see the Mini-PCI Specification rev 1.0 for pin layout and electrical
specifications, also, please see the “Bus Expansion” section for limitations.
4.4 JP1, Debug header
Debug connector for the AMD ElanSC520 processor. 10 pins 2mm header. Please see the Elan SC520
microcontroller users manual for more information.
4.5 JP2, CompactFlash socket
CompactFlash type I/II socket. This interfaces to the SC520 processor as an IDE controller, and can be set
for either the primary or secondary controller. Please see the Compact Flash Specification rev 1.4 for pin
layout, mechanical and electrical specifications.
4.6 JP3, User I/O
14 pins 0.050” header with 8 programmable general purpose input/output pins. They are connected directly
to the Elan SC520 processor, please see the Elan SC520 microcontroller users manual for programming
information and the Elan SC520 data sheet for electrical specifications. When the board is viewed as on the
illustration, pin 1 is the top left pin, at the “JP3” text.

4.7 JP6-JP8, Ethernet Jacks.
8 pins shielded RJ-45 jacks with built in LED’s for link status and network activity. Auto detects between
10baseT or 100baseT. When viewed from the rear, the left LED is link status, will be yellow when set for
10baseT and green when set for 100baseT, and the right LED will be green if there is network activity.
When software uses the BIOS PCI functions for searching for PCI devices, JP8 will be the first found, JP7
the second and JP6 the third found.
4.8 JP9, DC Power
6 pins AMP MTA100 header, for connecting of internal power supply. Also has 2 of the GP IO pins, for
use with advanced power management. Can be used with a 5V DC power supply if pin 3 and 4 are
connected together, or with a 6V – 20V DC power supply if only pin 3 are used. When the board is viewed
as on the illustration, pin 1 is the top pin, at the JP9 text.
