DFI MTH556-BCN-165H Intel Core Ultra 7 165H 3.5″ Single Board Computer with 9 to 36 V DC Input and Dual 2.5GbE

Multi-camera inspection cells and vision-guided machines often need to decode several video streams, run inference and drive an operator screen at the same time. The MTH556-BCN-165H is the build in the DFI MTH556 series aimed at that kind of load: a 3.5″ single board computer, 146 x 102 mm, designed to be integrated into an OEM enclosure or machine.

Its Intel Core Ultra 7 165H is a 16-core Meteor Lake processor with a 28 W TDP, running from 1.4 GHz up to 5.0 GHz, and the highest core count in the series. Intel Arc graphics decodes and encodes AV1, HEVC, VP9 and AVC in hardware, so camera feeds need not load the CPU cores. Two DDR5 SO-DIMM sockets take up to 96 GB at 5600 MHz, which leaves room for inference runtimes, image buffers and a local database on the same board.

HDMI, a USB-C port with DisplayPort Alt Mode and an internal dual-channel LVDS connector drive three independent displays, for example a local touch panel plus two monitors. Two 2.5GbE ports on Intel I226LM and I226V controllers can separate a camera network from the plant network. Three USB 3.2 Gen 2 Type-A ports, two internal USB 2.0 ports, two RS-232/422/485 ports, two RS-232 ports and 8-bit DIO connect cameras, controllers and field signals, and the M.2 M-key, B-key and E-key sockets take a PCIe Gen4 x4 SSD, a 4G or 5G module with nano SIM, and Wi-Fi.

The board runs from 9 to 36 V DC on a 4-pin connector and operates from -5 to 65 °C with the active cooler DFI supplies, which suits indoor cabinets and machine enclosures. It supports Windows 11 and 10 IoT Enterprise 64-bit or Linux, with TPM 2.0 and CE, FCC, UKCA, KC and RoHS compliance. The MTH556-BCN-135H offers 14 cores at the same 28 W for lighter vision loads, and the MTH556-ECN-255U runs 12 cores at 15 W with a wide -20 to 70 °C rating.
