DFI ADN253-N97 Intel N97 (Alder Lake-N) 4″ EPIC Single Board Computer with 9 to 36 V DC Input and Dual 2.5GbE

Self-service kiosks, ticket machines and information terminals combine a built-in screen with a row of serial peripherals: payment terminals, receipt printers, barcode readers and coin mechanisms. The ADN253-N97 is the Intel Processor N97 build in the DFI ADN253 series of 4″ EPIC single board computers, and it covers that mix on one board.

The Intel Processor N97 (Alder Lake-N) has four cores, with Intel UHD Graphics for browser-based interfaces and media playback. Memory is 8 GB of LPDDR5-4800 soldered to the board. The internal eDP or dual-channel LVDS connector drives the kiosk’s own panel directly, and the HDMI 1.4b output can feed a second screen for advertising or queue information.

Six COM ports take the peripherals: two RS-232/422/485 and two RS-232 on DB9, plus two RS-232 on internal headers, with 8-bit DIO selectable in BIOS in place of COM4 for door sensors or indicator lights. Three USB 3.2 Type-A ports, one USB 3.2 Type-C port and two USB 2.0 headers take a touch controller and card readers. Two 2.5GbE ports on Intel I226 and one GbE port on Intel I210 separate the payment network from the content network, and the M.2 B-key with SIM suits a cellular connection where there is no wired link.

The ADN253-N97 runs from 9 to 36 V DC on a barrel connector or 4-pin header and operates from -5 to 80 °C with 0.2 m/s airflow over its heatsink, with CE and FCC compliance and a TPM 2.0. For heavier interfaces or several applications, ADN253-N305 offers eight cores and 16 GB. For more memory on four cores, see ADN253-x7425E.
