DFI ADN553-BN-N50 Intel N50 (Alder Lake-N) 3.5″ Industrial Motherboard with 9 to 36 V DC Input and Triple 2.5GbE

A protocol gateway or data logger spends most of its life moving small amounts of data between networks, so it rarely needs many cores but often needs several ports and a cellular link. The ADN553-BN-N50 is built for that job: the dual-core entry option in the ADN553 series, a 3.5″ industrial motherboard with three 2.5GbE ports and M.2 sockets for 4G, 5G and Wi-Fi.

The Intel Processor N50 is a dual-core Alder Lake-N part running up to 3.4 GHz within a 6 W TDP. That suits Modbus or MQTT bridging, local buffering and a lightweight web interface, with little heat inside a small enclosure. One DDR5 4800 MHz SO-DIMM slot takes up to 16 GB, and Intel UHD Graphics supports a single-screen terminal or maintenance display. A discrete TPM 2.0 helps protect credentials on remote sites, and the watchdog can reset the board after a software hang.

Three 2.5GbE ports on Intel I226V controllers sit on the rear with two USB 3.2 Gen 2 and one USB 3.2 Gen 1 Type-A port, HDMI and USB-C with DisplayPort Alt Mode. An internal eDP connector supports a panel up to 4096 x 2160 at 60 Hz. Inside are two USB 2.0 headers, one RS-232/422/485 port and 8-bit DIO for field devices, one SATA 3.0 port, and M.2 M-key, B-key with SIM slot and E-key sockets.

The ADN553-BN-N50 runs fanless from -5 to 65 °C on 9 to 36 V DC, with CE, FCC, UKCA, KC and RoHS compliance. For twice the cores at the same 6 W, see the ADN553-BN-N200, which also switches to LVDS. The ADN553-BN-x7211E is the dual-core Atom alternative at 6 W, and for sites that reach -40 °C the Amston Lake ASL553 series is the wide-temperature option.
