March 02, 2017 // By Christoph Hammerschmidt
With its new PCOM-B642VG COM Express Basic module, Taiwan-based Portwell Inc. offers a single-board computer targeting IoT, medical/healthcare and retail applications. To make sure the device is powerful enough to deal with the challenges inherent to these applications, the PCOM-B642VG is equipped with Intel Core desktop processors of the 7th generation (codenamed Kaby Lake-S) and Q170, H110 and C236 Express chipsets. The company claims that despite higher computing power this design offers lower cost compared to mobile solutions.

The Portwell PCOM-B642VG COM Express module supports Intel Turbo Boost Technology via Intel Core i5 and i7 processors, Intel vPro Technology via Q170 chipset for superior remote capabilities and Intel Hyper-threading Technology via Intel Core i7 processors. It’s also designed with new advanced features offered by the 7 th generation Intel Core processors that boost IoT designs from the edge to the cloud, including Intel SGX (Software Guard Extensions), Intel MPX (Memory Guard Extensions), additional HSIO (High Speed Input/Output) with increased flexibility, and expanded HW/GPU accelerated codec support. In addition, the PCOM-B642VG delivers greater graphics performance, stunning Ultra HD 4K display across three independent displays, as well as faster 3-D and video playback capability, while maintaining improved energy efficiency. These enhanced features and performance translate into improved security and reduced manageability cost, making the Portwell PCOM-B642VG an ideal solution for Medical Healthcare Systems, Military Equipment, Retail Systems and IoT application design across a broad spectrum of industries. 

Specifically, the PCOM-B642VG COM Express module supports up to 32GB ECC (supported by C236 chipset only) and non-ECC DDR4 up to 2400MHz on two 288-pin SODIMM sockets, making it faster than its predecessor. Its expansion interface supports one PCI Express x16 Gen3 (8.0GT/s) for enhanced video performance, 1.6 times faster than the previous Gen2 (5.0GT/s), and eight PCI Express x1 Gen3 (8.0 GT/s). 

Furthermore, PCOM-B642VG supports three independent displays, DP (DisplayPort), VGA and eDP with greater 3D performance compared to its previous generation. The CPU’s TDP  is specified at 35 watts.


The PCOM-B642VG is developed on a basic 125mm x 95mm platform, and with the Intel Q170, H110, and C236 Express chipsets functioning smoothly with 7 th generation Intel Core processors. These features enable our customers to preserve their legacy components and subsequent investments while minimizing turn-around time – all of which ensures that the costs of inevitable upgrades are minimal.

As the markets evolve, Portwell’s versatile COM Express modules adapt to
