DFI ASL171 Intel Atom x7000RE and N150 Industrial Mini-ITX Motherboards with Dual 2.5GbE and -40 to 85 °C Options

Mini-ITX is still the simplest board size to drop into an existing cabinet: 170 x 170 mm, standard mounting holes and a wide choice of enclosures and panel mounts. The DFI ASL171 series brings Intel’s Amston Lake Atom x7000RE processors to that format, with an Intel Processor N150 (Twin Lake) build for projects that stay at room temperature. The boards are fanless, run from a single 12 V DC supply and keep the serial and digital I/O that control equipment still depends on.

Every ASL171 board takes one DDR5 4800 MHz SO-DIMM of up to 16 GB and uses Intel UHD Graphics with hardware decode for HEVC, VP9, AV1 and AVC. DP++ outputs drive 4K at 60 Hz, and the series supports three independent displays. An M.2 A-key accepts DFI’s optional M2A display module where a project needs an eDP, LVDS, VGA, HDMI or DP panel output on top of the rear connectors.

The range spans five builds. ASL171-CT-x7835RE carries the eight-core Atom x7835RE at 12 W for gateways and vision controllers running several tasks at once. ASL171-CT-x7433RE uses the quad-core x7433RE at 9 W with VGA, DP and USB-C display outputs for retrofit HMIs. ASL171-CT-x7213RE is a dual-core 9 W build with DP, HDMI and four rear USB 3.2 Gen 2 ports, and ASL171-CT-x7211RE is the dual-core 6 W build with two DP outputs for low-power control. These four run from -40 to 85 °C. ASL171-CB-N150 pairs the quad-core N150 with DP and HDMI for standard -5 to 65 °C installations such as signage and kiosks.

Across the range, two 2.5GbE ports on Intel I226IT controllers separate a plant network from a machine or camera network. Six COM ports on internal headers (two RS-232/422/485 and four RS-232) sit alongside 8-bit DIO, four internal USB 2.0 headers and at least three rear USB 3.2 Gen 2 ports. Expansion comes from an M.2 B-key (2242/3042/3052) with a Nano SIM socket for cellular modules, an M.2 E-key (2230) for Wi-Fi, a PCIe x4 slot with x2 Gen3 signaling and two SATA ports.

Power is 12 V DC on a barrel connector or 4-pin header. The boards carry CE, FCC, UKCA and RoHS compliance, a discrete TPM, a watchdog programmable from 1 to 255 seconds and support for Windows 10 IoT Enterprise LTSB, Windows 11 and Linux. Where the supply is a 24 V cabinet rail or a vehicle battery, the ASL173 series shares this layout with a 9 to 36 V DC input.
