DFI CS103-C246 Intel LGA 1151 Core Thin ITX Motherboard with C246 Chipset, Dual LAN and 9 to 36 V DC Input

A data logger in a substation kiosk or a controller on a test bench powered from 24 V may run for months between restarts, and a single-bit memory error can corrupt a long record. The CS103-C246 is the C246 build in the DFI CS103 series of Thin ITX motherboards, and it is the only CS103 board with ECC memory support.

The LGA1151 socket takes 8th and 9th Gen Intel Core i7, i5 and i3 processors at up to 65 W, from four to eight cores, 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 and bring Intel vPro and AMT on the I219LM port. Two SO-DIMMs at 2666 MHz hold up to 32 GB, and Intel UHD Graphics drives LVDS and two DP++ outputs, three at once.

The second GbE port runs on an Intel I210AT, so a field network and an uplink stay apart. 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 take meters, relays and alarms. NVMe at PCIe x4 on the M.2 M-key, two SATA 3.0 ports and RAID 0, 1 and 5 hold the logs, and an M.2 E-key and a PCIe x4 Gen3 slot take wireless and expansion.

The CS103-C246 accepts 9 to 36 V DC on a barrel or 4-pin connector and operates from -5 to 65 °C, with a TPM 2.0 and CE, FCC and RoHS compliance. CS103-Q370 has the same I/O and vPro without ECC, and CS103-H310 is the simpler build with dual display and USB 3.1 Gen 1.
