DFI PTH171 Intel Core Ultra Panther Lake Mini-ITX Motherboards with Triple 2.5GbE and 12 V DC Input

Mini-ITX is still the simplest board size to fit into an existing cabinet or a standard enclosure: 170 x 170 mm, standard mounting holes and a wide choice of chassis. The DFI PTH171 series brings Intel Core Ultra Series 3 (Panther Lake) processors to that format, with Intel Arc Xe3 graphics and Intel vPro on every build. It is aimed at OEMs moving vision, inference and multi-screen control onto one board, and it runs from a single 12 V DC supply.

Two DDR5 SO-DIMM slots take up to 128 GB in dual channel, at up to 7200 MHz on the H-series processors. Arc Xe3 graphics drive HDMI 2.0 at 4096 x 2160 and DP++ at 4096 x 2304, both at 60 Hz, and a rear USB-C port adds a third display through DisplayPort Alt Mode. A fourth display comes from DFI’s optional display module on the M.2 A-key, with eDP, LVDS, VGA, DP or HDMI for an internal panel. Every board is cooled by an active CPU cooler.

The range spans six builds in two groups. The -IB- builds run from -5 to 65 °C and are M.2 only: PTH171-IB-U9388H carries the Core Ultra 9 388H and PTH171-IB-UX7358HR the Core Ultra X7 358HR, both with the larger 12 Xe-core graphics configuration for vision and display-heavy work. The -IE- builds are rated for wide temperature, -20 to 70 °C, and add a PCIe Gen5 x4 slot. PTH171-IE-U7366HRE and PTH171-IE-U5336HRE use the HRE processors, while PTH171-IE-U7365RE and PTH171-IE-U5335RE use the RE parts, which DFI lists at 15 W, for sealed cabinets where heat is the limit.

Three 2.5GbE ports on Intel I226V and I226LM controllers keep a plant network, a camera network and an uplink apart, with vPro remote management on the I226LM port. Rear USB covers two USB 3.2 Gen 2, two USB 3.2 Gen 1 and one USB 2.0 Type-A port, with five more USB 2.0 on internal headers. Four COM ports (two RS-232/422/485 and two RS-232) and 8-bit DIO sit on internal headers. Storage comes from an M.2 M-key (2242/2280) with PCIe Gen5 x4 or SATA and two SATA ports, and an M.2 B-key with Nano SIM and an M.2 E-key (2230) take cellular and Wi-Fi modules.

Power is 12 V DC on a barrel connector or 4-pin connector. The boards carry CE, FCC, UKCA and RoHS compliance, a discrete TPM, a watchdog programmable from 1 to 255 seconds, Realtek ALC888S audio and support for Windows 11 24H2 LTSC and Ubuntu 24.04. Where the supply is a 24 V cabinet rail, the PTH173 series shares this layout with a 12 to 28 V DC input.
