1Introduction
The COM Express approach of custom carrier combined with off the shelf system cores is an
excellent solution when you need to customize but lack the time or quantity for a complete
redesign. It fits most system integration projects with production volumes from 500 to 10,000 pcs
per year. The COM Express concept has a great many advantages over full custom designs, it
reduces engineering complexity, lowers the threshold for total project quantity and last but not
least brings your product to the market in no time. The average time to design a carrier board is
less than half the time of a full custom OEM board.
Express-BASE is a standardATX size carrier board. Together with the COM Express module of
your choice and off the shelf add-on cards you can quickly emulate the functionality of your
desired end product for software development and hardware verification.
To build a functional prototype of your target system you will need:
fCOM Express module
fExpress-BASE carrier board
fPCI Express or PCI add on cards
fPATA/ SATAstorage or Flash disk solution
Express-BASE accommodates up to five PCI Express x1 slots, one PCI Express Graphics x16
slot, one ExpressCard slot and one PCI slot.
The board is based on PICMG’s COM Express specification and is compatible with:
Standard form factor Type 2 COM Express modules

2Special Features
2.1 Primary LPC based Super I/O
Express modules do not contain any Super I/O because this is considered legacy. Therefore
Super I/O is placed on the carrier board as an optional item. The Express-BASE uses a Winbond
W83627HG-AW that supports FDD, LPT, COM and PS/2 Keyboard and Mouse.
2.2 Secondary LPC based BIOS
Express-BASE contains a socket for secondary LPC BIOS on board in addition to the soldered
BIOS on the Express module. Selection of active BIOS can be done by jumper settings
2.3 Integrated Debug Port with Single Step Execution
In addition to a two digit POST code display the board also provides four digits display for ad-
dress. By jumper selection the board can be switched into single step BIOS execution mode.
Steps are executed using a manually operated on board mini switch.
2.4 Audio Codec
The onboard stereo audio power amplifier contains two identical amplifiers capable of delivering
6 W per channel of continuous average power into a 4-W load at 10% THD+N or 5 W per channel
at 1% THD+N. The gain of each channel is fixed at 20 dB. The amplifier features a mute/standby
function for power-sensitive applications.
2.5 Information LEDs
General information is obtained through signalling LEDs for HDD, Power and Watchdog status.
Additionally the Express-BASE give information about module types being plug into the board.
