DFI CS332 Intel Coffee Lake Core Micro-ATX Motherboards with C246 or Q370 Chipset and Quad LAN

Gateways, recorders and inspection PCs often need more than two network ports: one for the plant network, one for the office side and more for cameras or instruments. The DFI CS332 series is a Micro-ATX industrial motherboard on a 244 x 244 mm footprint with two Intel GbE ports as standard and a four-port build available to order, on an LGA1151 socket for 8th and 9th Gen Intel Core processors.

The socket takes Core i7-8700, i5-8500 and i3-8100 in 65 W and 35 W T versions, the 9th Gen embedded Core i7-9700E, i7-9700TE, i5-9500E, i5-9500TE, i3-9100E and i3-9100TE, plus dual-core Pentium G5400 and Celeron G4900. That spans two to eight cores, and DFI rates the socket for processors up to 95 W. Four DDR4 2666 MHz DIMM slots take up to 128 GB. Intel UHD Graphics drives VGA and two DP++ outputs as three independent displays, and Intel AMT on the I219LM port works with Core i5 and i7.

The CS332-C246 uses the Intel C246 chipset, which adds ECC memory support with Core i3, Pentium and Celeron and four USB 3.2 Gen 1 ports on the rear panel. The CS332-Q370 uses the Q370 chipset with non-ECC memory and two rear USB 3.2 Gen 1 ports, for systems where ECC is not part of the specification. Both carry the same slots, storage and network options.

Storage covers an M.2 M-key socket for PCIe x4 Gen3 NVMe SSDs in 2242 or 2280 sizes and four SATA 3.0 ports with RAID 0, 1, 5 and 10. An M.2 E-key 2230 socket and a full-size Mini PCIe slot take Wi-Fi or other modules. Expansion is a PCIe x16 Gen3 slot, two PCIe x4 Gen3 slots and a PCI slot. Serial runs to four COM ports, one RS-232/422/485 on a rear DB-9 and three RS-232 on headers, with 8-bit digital I/O.

Power comes from a standard ATX supply over 24-pin and 8-pin connectors, and an active CPU cooler keeps the boards within 0 to 60 °C in indoor cabinets and racks. TPM 2.0 and a watchdog timer programmable from 1 to 255 seconds or minutes support secure, unattended operation, and the CS332 series carries CE, FCC, RoHS and UL compliance.
