DFI ARS310 Intel Core Ultra 200S LGA 1851 Micro-ATX Industrial Motherboards with W880 or Q870 Chipset and Dual 10GbE Options

Some industrial systems need more than a small board can carry: a frame grabber and a GPU side by side, a bank of serial devices, several drives and memory measured in hundreds of gigabytes. The DFI ARS310 series puts that on a 244 x 244 mm Micro-ATX motherboard built around the LGA 1851 socket for Intel Core Ultra 200S (Arrow Lake-S) processors, powered from a standard ATX supply.

DFI lists eight processors: the Core Ultra 9 285 and 285T with 24 cores, the Core Ultra 7 265 and 265T with 20, and the Core Ultra 5 245, 245T, 225 and 225T with 14 or 10 cores, at 65 W or 35 W, and the board supports processors up to 125 W TDP. Four DDR5 DIMM slots run in dual channel at up to 5600 MHz and hold up to 256 GB. Integrated Intel graphics drives VGA, two DP++ and HDMI 2.0a outputs for four independent displays, with DP++ at up to 4096 x 2304 and 60 Hz.

Two chipset builds make up the range. ARS310-W880 uses the Intel W880 chipset with ECC memory support and two 2.5GbE ports, and it is available with optional dual 10GbE (Intel E610) for camera aggregation, storage traffic or a fast uplink. ARS310-Q870 uses the Q870 chipset with two 2.5GbE ports and non-ECC memory, for test and control systems where the network load is lighter.

Both boards carry two PCIe x16 Gen5 slots, which share the processor’s lanes as one x16 or two x8, plus two PCIe x4 Gen4 slots. One M.2 M-key runs NVMe at PCIe Gen5 x4, a second takes NVMe at Gen4 x4 or SATA, and a 2230 E-key takes Wi-Fi. Four SATA 3.0 ports support RAID 0, 1, 5 and 10. The rear panel has four USB 3.2 Gen 2 and four USB 3.2 Gen 1 ports, and internal headers add two USB 3.2 Gen 1, three USB 2.0, six COM ports (two RS-232/422/485 and four RS-232) and 4-in/8-out DIO.

Power comes from an ATX supply on 24-pin and 8-pin connectors. The ARS310 series operates from -5 to 65 °C with CE, FCC, UKCA, RoHS and KC compliance, a TPM 2.0, a watchdog programmable from 1 to 255 seconds and Realtek ALC888 audio with S/PDIF. DFI lists Windows 10 IoT Enterprise, Windows 11 LTSC and Linux.
