DFI ADN553 Intel Alder Lake-N 3.5" SBCs with Triple 2.5GbE and 9 to 36 V DC Input

Many compact industrial designs need more network ports than a small board usually offers: a controller that talks to a machine network, a plant network and a camera, or a kiosk that keeps payment traffic apart from content updates. The DFI ADN553 series answers that on the 146 x 102 mm 3.5″ footprint, with three 2.5GbE ports on every board and a panel output for a built-in display. These 3.5″ SBCs are boards for integration into your own enclosure, so the choice comes down to processor, panel interface and power budget.

Every ADN553 board uses an Intel Alder Lake-N processor with Intel UHD Graphics and one DDR5 4800 MHz SO-DIMM slot for up to 16 GB in single channel. The graphics engine decodes HEVC, VP9, AV1 and AVC in hardware, which keeps signage and video playback off the CPU cores. A discrete TPM 2.0, a programmable watchdog timer and Realtek ALC888S audio are common to the range, and DFI lists support for Windows 10 IoT Enterprise, Windows 11 and Linux.

The range runs from low-power dual-core parts to eight cores. The ADN553-BN-N50 (dual-core, 6 W) and ADN553-BN-x7211E (dual-core Atom, 6 W) suit simple controllers and thin clients, both with an eDP panel output. The ADN553-BN-x7213E keeps two Atom cores at 10 W with LVDS. For quad-core headroom, the ADN553-BN-N200 runs at 6 W with LVDS, the ADN553-BN-N97 at 12 W with eDP and the ADN553-BN-x7425E at 12 W with LVDS. The ADN553-BN-N305 brings eight cores at 15 W for gateways, multi-camera capture and heavier HMI software.

Rear I/O covers three 2.5GbE ports on Intel I226V controllers, two USB 3.2 Gen 2 and one USB 3.2 Gen 1 Type-A port, HDMI up to 4096 x 2160 and a USB-C port with DisplayPort Alt Mode up to 3840 x 2160 at 60 Hz, giving three independent displays with the internal panel. Internal headers add two USB 2.0 ports, one RS-232/422/485 port and 8-bit digital I/O. Three M.2 sockets cover a PCIe or SATA SSD, a 4G or 5G modem through a B-key socket with SIM slot, and Wi-Fi through an E-key socket, alongside one SATA 3.0 port.

Power comes in at 9 to 36 V DC through a 4-pin connector or a barrel connector, so the boards run from 12 or 24 V supplies without a separate converter. The supplied passive heatsink keeps every ADN553 board fanless across its -5 to 65 °C operating range, which suits indoor cabinets, kiosks and control panels. The series carries CE, FCC, UKCA, KC and RoHS compliance.
