DFI PTH173 Intel Core Ultra Panther Lake Industrial Mini-ITX Motherboards with 12 to 28 V DC Input and Triple 2.5GbE

Many industrial cabinets and mobile machines distribute 24 V DC, not 12 V, and a board that takes that rail directly saves a converter and a point of failure. The DFI PTH173 series brings Intel Core Ultra Series 3 (Panther Lake) processors to the Mini-ITX format with a 12 to 28 V DC input, so the same 170 x 170 mm board runs from a 12 V supply or a 24 V cabinet rail. Every build has Intel Arc Xe3 graphics and Intel vPro.

Memory is two DDR5 SO-DIMM slots in dual channel, taking up to 128 GB and running at up to 7200 MHz on the H-series processors. HDMI 2.0 and DP++ outputs drive 4K screens at 60 Hz, and a rear USB-C port with DisplayPort Alt Mode adds a third. DFI’s optional module on the M.2 A-key provides a fourth display as eDP, LVDS, VGA, DP or HDMI, which suits an internal operator panel. An active CPU cooler is fitted on every board.

There are six builds. Two -IB- builds operate from -5 to 65 °C and are M.2 only: PTH173-IB-U9388H with the Core Ultra 9 388H and PTH173-IB-UX7358HR with the Core Ultra X7 358HR, both carrying the larger 12 Xe-core graphics configuration for vision and multi-screen work. Four -IE- builds are rated for wide temperature, -20 to 70 °C, and add a PCIe Gen5 x4 slot: PTH173-IE-U7366HRE and PTH173-IE-U5336HRE on the HRE processors, and PTH173-IE-U7365RE and PTH173-IE-U5335RE on the RE parts, which DFI lists at 15 W.

Three 2.5GbE ports on Intel I226V and I226LM controllers separate machine, camera and uplink networks, and the I226LM port supports vPro remote management. At the rear are two USB 3.2 Gen 2, two USB 3.2 Gen 1 and one USB 2.0 Type-A port, with five USB 2.0 on internal headers. Four COM ports (two RS-232/422/485, two RS-232) and 8-bit DIO sit on headers. An M.2 M-key (2242/2280) with PCIe Gen5 x4 or SATA takes an NVMe SSD, an M.2 B-key with Nano SIM takes a cellular module, an M.2 E-key (2230) takes Wi-Fi, and two SATA ports add drives.

Power is 12 to 28 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 and Realtek ALC888S audio, with support for Windows 11 24H2 LTSC and Ubuntu 24.04. For a fixed 12 V supply, the PTH171 series shares this layout.
