DFI CS551-Q370-BCA Intel LGA 1151 Core 3.5″ Embedded Board with Q370 Chipset, Dual LAN and 12 V DC Input

Vision inspection cells and data-heavy HMIs write images and logs quickly and often connect USB cameras, so storage and USB bandwidth matter as much as the processor. The CS551-Q370-BCA is the Q370 chipset build of the DFI CS551 series, a 3.5″ embedded board that pairs an LGA1151 socket with USB 3.1 Gen 2 and a PCIe x4 M.2 socket.

The socket takes 8th and 9th Gen Intel Core T and TE processors (Coffee Lake) at 35 W. The eight-core Core i7-9700TE and the six-core i7-8700T, i5-8500T and i5-9500TE suit image processing, while the four-core Core i3-8100T and i3-9100TE and the dual-core Pentium G5400T and Celeron G4900T cover lighter HMIs. One DDR4 2666 MHz SO-DIMM takes up to 32 GB. Intel UHD Graphics 630 drives two DP++ outputs at up to 4096 x 2304 at 60 Hz and 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 drives, and the M.2 M-key 2280 socket runs PCIe x4 NVMe or SATA SSDs, with a SATA 3.0 port beside it. Two GbE ports use Intel I211AT or I210IT controllers, and a full-size mini PCIe socket with an optional SIM slot takes Wi-Fi or 4G. Headers add two USB 2.0 ports, an RS-232/422/485 port, 8-bit DIO and Realtek ALC262 audio.

The CS551-Q370-BCA runs from 12 V DC on a 4-pin connector, or a barrel jack on request, and is rated from -5 to 65 °C with 35 W processors, with CE, FCC, UKCA and RoHS compliance; a fanless heatsink is standard and a cooler fan optional. The CS551-C246-BCA adds ECC memory support with the same I/O, and the CS551-Q370-ECA extends this build to -30 to 80 °C.
