Linux-friendly COM Express module floats 3rd Gen Cores

Jul 30, 2015 — by Rick Lehrbaum — 433 views

Acrosser has introduced a pair of COM Express Type 6 Basic modules based on circa-2013 Core i7/i3 CPUs from Intel’s extended lifecycle, embedded roadmap.

Being compatible with PICMG’s COM Express Type 6 Basic specifications, Acrosser’s “AMB-HM76B1” computer-on-module has much in common with other embedded board vendors’ products in the same form factor. In Acrosser’s case, the module is offered in two versions, offering the choice of fan or passive heatspreader cooling solutions. With this release, the company has doubled its COM Express module product line, adding to the one it rolled out in late-2012.

In addition to offering two heat dissipation configurations, the AMB-HM76B1 comes in three SKUs, based three dual-core, 17W TDP, 3rd Generation Intel processors: the 1.7GHz Core i7 3517UE, the 1.GHz Core i3 3217U, or the 1.4GHz Celeron 1047UE. The module’s design teams these processors up with Intel’s QM7 mobile chipset.

Acrosser’s Linux support for the AMB-HM76B1 comes in the form of Linux 3.3-based Fedora 17 32 and Linux 3.5-based Ubuntu 12.10. However, in light of the chipsets used, we imagine most any modern Linux kernel or distribution will run fine on the boards. Windows 7 is also supported.

Another pair of COM Express modules based on Intel’s 3rd Generation Intel Core and Celeron processors and HM76 mobile chipset was introduced by Congatec about two years ago. Congatec’s Conga-BS77 and Conga-TS77 (shown below) are implemented according to PICMG Type 2 and Type 6 bus specifications, respectively, and are available in a wide range of Core and Celeron processor SKUs.

Development baseboard

Although no reference to a COM Express Type 6 carrier board appeared in Acrosser’s announcement of the AMB-HM76B1 or currently shows up on either of the AMB-HM76B1’s product pages, an ACM-B4080 carrier board for COM Express Basic Type 6 COMs is listed on the COM Express family page of Acrosser’s website. We presume it supports HM7681-based development.

The image above identifies the key features of the ACM-B4080 baseboard, which, among others, include 1x VGA port, 2x HDMI ports, 4x SATA interfaces, 8x USB ports; GPIO, 1x PCIe x16 slot, 1x PCIe x4 slot, 3x PCIe x1 slots, and a pair of sockets where you plug-in the COM Express module.
