DFI ARS101-Q870 Intel Arrow Lake-S Core Ultra Thin ITX Motherboard with Q870 Chipset, Dual 2.5GbE and 12 V DC Input

A retail kiosk estate or a fleet of self-service terminals is usually managed from one office, and a site visit to restart a frozen unit can cost more than the board. The ARS101-Q870 is the Q870 build in the DFI ARS101 series of Thin Mini-ITX motherboards, and it brings Intel AMT remote management to a slim, socketed Intel Core Ultra 200S design on 12 V DC.

The LGA 1851 socket accepts eight Arrow Lake-S processors: the 24-core Core Ultra 9 285 and 285T, the 20-core Core Ultra 7 265 and 265T, and the Core Ultra 5 245, 245T, 225 and 225T with 14 or 10 cores. The T parts run at 35 W for tight thermal budgets, the others at 65 W. Two DDR5 SO-DIMMs hold up to 96 GB in dual channel, and integrated Intel graphics drives HDMI 1.4b, DP++ and USB-C display outputs at 4K, with an optional M2A module for an eDP or LVDS panel.

Six rear USB 3.2 Gen 2 Type-A ports and four internal USB 2.0 headers leave room for card readers, barcode scanners, printers and a touch controller. Two 2.5GbE ports on Intel I226-LM and I226-V, two RS-232/422/485 headers and 8-bit DIO handle the network and serial devices. The PCIe x16 Gen5 slot takes one x16 card or two x8 links, and four M.2 sockets add NVMe storage at PCIe Gen4 x4, a cellular module with Nano SIM, Wi-Fi and a display module, with two SATA 3.0 ports for further drives.

Power is 12 V DC on a barrel jack or 4-pin connector, and the ARS101-Q870 operates from -5 to 65 °C with CE, FCC, UKCA and RoHS compliance. Choose ARS101-W880 when the application needs ECC memory as well as AMT, or ARS101-H810 when a straightforward kiosk or signage build needs neither.
