Expandable Mini-ITX SBC runs Linux on 1.8GHz Atom

Sep 16, 2013 — by Eric Brown 2,397 views

Acrosser announced a Fedora Linux-ready Mini-ITX single board computer (SBC) equipped with a dual-core 1.86GHz Intel Atom D2550. The AMB-D255T3 supports up to 4GB of DDR3 RAM, can run dual displays via VGA, HDMI, or 18-bit LVDS interfaces, and offers both PCI and mini-PCIe expansion.

The Intel Atom D2550-based “Cedar Trail” platform has been a popular choice for vendors offering 6.7 x 6.7-inch Mini-ITX boards. D2550-based Mini-ITX boards are available from Advantech, ASRock, Giada, Jetway, and Portwell, among others, ranging in price from $150 to $300. Acrosser did not post a price for its AMB-D255T3 contribution to the genre, which unlike some of its competitors features a legacy PCI slot, as well as Mini-PC-Express expansion. The mini-PCIe socket works with SATA and USB signals that can be equipped with an mSATA module, says the company.

The board’s Atom D2550 processor features dual cores clocked to 1.86GHz, and offers an Intel GPU frequency of 640MHz and a 10 Watt TDP. Hyperthreading is available, but there’s no support for virtualization.

    There is a good chance that just about every x86 based Linux distro can be used with this machine. ;)
