DFI CS101-C246 Intel LGA 1151 Core Thin Mini-ITX SBC with C246 Chipset, Dual LAN and 12 V DC Input

Slim test equipment, analysers and control terminals that log results over long runs benefit from memory that corrects single-bit errors, even when the enclosure only has room for a Thin Mini-ITX board. The CS101-C246 is the C246 build in the DFI CS101 series of Thin Mini-ITX SBCs, and it is the only CS101 board with ECC memory support.

The LGA1151 socket takes 8th and 9th Gen Intel Core i7, i5 and i3 processors, from four to eight cores and up to the Core i7-9700K at 95 W, as well as the Pentium G5400 and Celeron G4900. ECC DDR4 works with the Core i3, Pentium and Celeron parts; Core i5 and i7 run non-ECC memory but bring Intel vPro and AMT on the I219LM port. Two SO-DIMMs at 2400/2666 MHz hold up to 32 GB, and Intel UHD Graphics drives three displays.

Display outputs are HDMI and two DP++ at the rear with an internal LVDS or eDP connector. A second GbE port runs on an Intel I210AT, and four USB 3.1 Gen 2 ports sit at the rear with four USB 2.0 ports inside. Two RS-232/422/485 and two RS-232 ports on internal headers and 8-bit DIO connect instruments. NVMe at PCIe x4 on the M.2 M-key, Mini PCIe with mSATA, two SATA 3.0 ports and RAID 0, 1 and 5 cover storage.

The CS101-C246 runs from 12 V DC on a barrel or 4-pin connector and operates from 0 to 60 °C, with a TPM 2.0 and CE, FCC, UL, UKCA and RoHS compliance. CS101-Q370 has the same I/O and vPro without ECC, and CS101-H310 is the simpler build with dual display and USB 3.1 Gen 1.
