DFI ADN173 Intel N100 and Atom x7000E Mini-ITX SBCs with 9 to 36 V DC Input and Dual 2.5GbE

Machine builders rarely get to choose their supply rail. One installation runs on 12 V, the next on a 24 V cabinet supply, and a battery-backed system drifts between the two. The DFI ADN173 series handles that with Mini-ITX SBCs that accept 9 to 36 V DC, built on Intel Alder Lake-N processors and cooled by a passive heatsink on a standard 170 x 170 mm board.

Every ADN173 board takes one DDR5 4800 MHz SO-DIMM in single channel, and Intel UHD Graphics support three independent displays with hardware decode of HEVC, VP9, AV1 and AVC. A discrete TPM is fitted as standard, the watchdog timer is programmable from 1 to 255 seconds, and Realtek ALC888S audio provides line-out.

Six builds make up the range. The ADN173-CB-N50 is a dual-core 6 W board with two DisplayPort outputs and USB-C, and the ADN173-CB-x7213E pairs a dual-core Atom x7213E at 10 W with DisplayPort, HDMI 2.0 and support for 32 GB of memory. The ADN173-CB-x7425E is the quad-core Atom build at 12 W, with VGA, DisplayPort and USB-C outputs. The ADN173-CB-N97 gives four cores at 12 W with two DisplayPort outputs and 32 GB memory support, the ADN173-CB-N100 brings the Intel N100 with two DisplayPort outputs, and the ADN173-CB-i3-N305 tops the range with eight cores at 15 W, DisplayPort and HDMI 2.0.

Across the series, two Intel I226V 2.5GbE ports handle networking, and six COM ports on internal headers (two RS-232/422/485 and four RS-232) plus an 8-bit DIO connect PLCs, meters and discrete signals. Three USB 3.2 Gen 2 Type-A ports sit on the rear with four USB 2.0 on headers. Expansion is an M.2 B-key with Nano SIM socket for an SSD or cellular module, an M.2 E-key for wireless, an M.2 A-key for DFI’s optional M2A display module, two SATA 3.0 ports and a PCIe x4 slot at x2 Gen3.

Power arrives on a barrel jack or 4-pin connector, and the boards operate from -5 to 65 °C, suiting indoor cabinets and machine enclosures. DFI lists CE, FCC, UKCA, RoHS and KC compliance, with support for Windows 10 IoT Enterprise LTSB, Windows 11 and Linux. For a fixed 12 V supply, the same board is available as the ADN171.
