DFI CS551-H310-ECA Intel Coffee Lake Core 3.5″ Single Board Computer with H310 Chipset, Dual LAN and Wide Temperature

Controllers for car park barriers, pumping stations or agricultural machinery sit in enclosures with no heating and little cooling, but rarely need the fastest storage. The CS551-H310-ECA is the H310 chipset build of the DFI CS551 series in its wide temperature form, a 3.5″ single board computer rated from -30 to 80 °C with a socketed Intel Core processor.

The LGA1151 socket takes 8th and 9th Gen Intel Core T and TE processors (Coffee Lake): the four-core Core i3-8100T and i3-9100TE and the dual-core Pentium G5400T and Celeron G4900T for control tasks, or the six- and eight-core Core i5 and i7 parts for heavier loads. For the -30 to 80 °C rating, DFI sets the processor to a 15 W TDP-down. One DDR4 2666 MHz SO-DIMM takes up to 32 GB, and Intel UHD Graphics 630 runs two DP++ outputs at up to 4096 x 2304 at 60 Hz plus dual-channel LVDS.

The H310 chipset gives four USB 3.1 Gen 1 Type-A ports and an M.2 M-key 2280 socket for a PCIe x1 NVMe or SATA SSD, with a SATA 3.0 port for a second drive. Two GbE ports use Intel I211AT or I210IT controllers, and a full-size mini PCIe socket with an optional SIM slot can hold a 4G module for remote sites. Headers carry two USB 2.0 ports, an RS-232/422/485 port, 8-bit DIO and Realtek ALC262 audio.

The CS551-H310-ECA runs from 12 V DC on a 4-pin connector, or a barrel jack on request, with a 12 V heater header for starts at the cold end of its -30 to 80 °C range, a fanless heatsink as standard, and CE, FCC, UKCA and RoHS compliance. The CS551-Q370-ECA adds USB 3.1 Gen 2 and a PCIe x4 M.2 socket at the same rating, and the CS551-H310-BCA is the indoor build at -5 to 65 °C with full 35 W processors.
