DFI ARS310-Q870 Intel Arrow Lake-S Core Ultra Micro-ATX Industrial Motherboard with Q870 Chipset, Dual 2.5GbE and PCIe Gen5 x16

Automated test equipment and lab systems tend to collect add-in cards: a data acquisition card, a motion controller, a GPU for analysis, perhaps an interface for older instruments, alongside a rack of serial devices. The ARS310-Q870 is the Q870 build in the DFI ARS310 series of Micro-ATX industrial motherboards, giving those systems four expansion slots and six COM ports around a socketed Intel Core Ultra 200S processor.

Eight Arrow Lake-S processors fit the LGA 1851 socket: 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 for the T parts. Four DDR5 DIMMs in dual channel at up to 5600 MHz hold up to 256 GB. Integrated Intel graphics drives VGA, two DP++ and HDMI 2.0a outputs, so an older VGA monitor and 4K screens can run together.

Two PCIe x16 Gen5 slots run as x16 or x8/x8 and two PCIe x4 Gen4 slots take further cards. Two 2.5GbE ports on Intel I226-LM and I226-V connect the test network and the factory system. Internal headers provide two RS-232/422/485 and four RS-232 ports, 4-in/8-out DIO, two USB 3.2 Gen 1 and three USB 2.0, with four USB 3.2 Gen 2 and four Gen 1 ports at the rear. An M.2 NVMe slot at PCIe Gen5 x4, a second at Gen4 x4 or SATA, a Wi-Fi E-key and four SATA 3.0 ports with RAID 0/1/5/10 cover storage.

The ARS310-Q870 draws power from an ATX supply on 24-pin and 8-pin connectors and operates from -5 to 65 °C, with CE, FCC, UKCA, RoHS and KC compliance. Where the system aggregates camera streams or needs ECC memory, ARS310-W880 adds ECC support and optional dual 10GbE on the W880 chipset.
