DFI CS551-Q370-ECA Intel LGA 1151 Core 3.5″ Industrial Motherboard with Q370 Chipset, Dual LAN and -30 to 80 °C

Outdoor kiosks, traffic monitoring and ALPR cabinets record images or video locally and need to keep doing so through winter nights and summer afternoons. The CS551-Q370-ECA is the Q370 chipset build of the DFI CS551 series in wide temperature form, a 3.5″ industrial motherboard rated from -30 to 80 °C with USB 3.1 Gen 2 and PCIe x4 NVMe storage.

The LGA1151 socket takes 8th and 9th Gen Intel Core T and TE processors (Coffee Lake), from the dual-core Celeron G4900T and Pentium G5400T and four-core Core i3 parts to the six-core i5-9500TE and eight-core i7-9700TE. DFI rates this build with the processor set to a 15 W TDP-down. One DDR4 2666 MHz SO-DIMM takes up to 32 GB, and Intel UHD Graphics 630 drives two DP++ outputs at up to 4096 x 2304 at 60 Hz plus dual-channel LVDS at up to 1920 x 1200, as three independent displays.

Four USB 3.1 Gen 2 Type-A ports connect cameras and external storage, and the M.2 M-key 2280 socket runs PCIe x4 NVMe or SATA SSDs for recording, with a SATA 3.0 port for a second drive. Two GbE ports on Intel I211AT or I210IT controllers, a full-size mini PCIe socket with an optional SIM slot for 4G, two internal USB 2.0 ports, an RS-232/422/485 header, 8-bit DIO and Realtek ALC262 audio complete the I/O.

The CS551-Q370-ECA runs from 12 V DC on a 4-pin connector, or a barrel jack on request, across -30 to 80 °C, with a 12 V heater header for cold starts, a fanless heatsink as standard and CE, FCC, UKCA and RoHS compliance. The CS551-C246-ECA adds ECC memory support at the same rating, and the CS551-Q370-BCA is the indoor build at -5 to 65 °C with processors at their full 35 W.
