Please note: This is an End of Life (EOL) product. We strongly recommend transitioning over to the Intel DN2800MT Marshalltown motherboard.
Note: While this motherboard comes with a fanless heatsink it requires active cooling either via case fans or a purpose-built heatsink. For our fanless system configurations, please see our Fanless Computers.
The D945GSEJT ("Johnstown") is Intel's Mini-ITX
Atom-based solution featuring the N270 processor and efficient 945GSE chipset. Targeted specifically at the embedded, low-power computing
market, the Johnstown is an ultra thin (< 20 mm thick), fanless mainboard. Offering onboard 12-volt DC power, it has the potential to have an extremely small footprint and is excellent for use in custom enclosures or other embedded systems. With more I/O capabilities than its predecessors (Little Falls series), the Johnstown mainboard is versatile—featuring DVI and LVDS, Gb LAN, wireless connectivity (via PCIe Mini Card), and digital audio. Still incredibly
affordable, even with all the platform improvements from the Little Falls series, the Johnstown is
an excellent solution for a wide range of embedded and Internet centric applications.
For even more versatility, select the Broadcom CrystalHD video decoder for full 1080p playback.
Please note: LVDS is not enabled by default; it is intended for system integration. Project customers who require LVDS functionality, please contact a technical sales associate at 802 861 2300, option1 for more information.
Please choose “Mainboard Test” to ensure that the board is free from manufacturer’s defects, errors, etc. If “Mainboard Test” is selected, please allow 1-2 full business days for completion before shipment date.
