DFI ARH171 Intel Core Ultra Arrow Lake and Meteor Lake Industrial Mini-ITX Motherboard with Triple 2.5GbE and 12 V DC Input

A compact vision station, a self-service kiosk or an operator panel now often runs an AI model beside its main application, and it has to fit that into a small enclosure on a 12 V supply. The ARH171 is a DFI industrial Mini-ITX motherboard built for that job, with Intel Core Ultra mobile processors soldered on board and every listed Arrow Lake and Meteor Lake H and U option available.

The 28 W H-series parts, the Core Ultra 7 265H, 255H, 165H and 155H and the Core Ultra 5 235H, 225H, 135H and 125H, suit multi-camera inference and heavier graphics. The 15 W U-series parts with the same model numbers suit cooler, quieter designs, and they can be fitted with a fanless heatsink on request, while the H parts use an active cooler as standard. The 265, 235, 165 and 135 processors support Intel vPro. Two DDR5 5200 MHz SO-DIMMs hold up to 128 GB, and DFI lists OpenVINO, DirectML and ONNX Runtime support on the integrated graphics, which is Intel Arc on the H parts.

Three 2.5GbE ports on Intel I226-V and I226-LM controllers separate cameras, the machine network and a managed uplink. DP++ and HDMI outputs at 4K, a USB-C port with DisplayPort Alt Mode and DFI’s optional M2A panel module give four displays. Four rear USB 3.2 Gen 2 ports, four internal USB 2.0 headers, four COM ports and 8-bit DIO handle peripherals. An M.2 M-key runs NVMe at PCIe Gen4 x4, a B-key with Nano SIM takes a cellular module, an E-key takes Wi-Fi, and a PCIe x4 Gen4 slot and two SATA 3.0 ports add expansion.

The ARH171 takes 12 V DC on a barrel jack or 4-pin connector and operates from -5 to 65 °C, with CE, FCC, UKCA and RoHS compliance, a discrete TPM and a watchdog programmable from 1 to 255 seconds. DFI lists Windows 11 IoT Enterprise LTSC and Linux. For 24 V cabinets or battery supplies, the ARH173 is the same board on 12 to 28 V DC.
