DFI ASL051 Intel Atom x7000RE and N-Series 2.5" Pico-ITX SBCs with Dual 2.5GbE, HDMI and LVDS

A 2.5″ board often ends up where a larger computer cannot go: behind an operator panel, inside a vehicle console or in a roadside or trackside cabinet. The DFI ASL051 series serves those installations with two processor families on one 100 x 72 mm Pico-ITX design, so a single board layout can cover both indoor products and wide-temperature ones.

Every ASL051 board has a single DDR5 SO-DIMM socket for up to 16 GB at 4800 MHz, Intel UHD Graphics and passive heatsink cooling. Graphics output is HDMI at up to 4096 x 2160 at 24 Hz and dual-channel 18/24-bit LVDS at up to 1920 x 1200, driving two independent displays, with hardware decode of HEVC, VP9, AV1 and AVC.

The TTD builds use Intel Atom x7000RE (Amston Lake) processors and operate from -40 to 85 °C: the ASL051-TTD-x7835RE with eight cores at 12 W, the ASL051-TTD-x7433RE with four cores at 9 W and the ASL051-TTD-x7211RE with two cores at 6 W. The BCD builds use Intel N-series processors and operate from -5 to 65 °C: the ASL051-BCD-N355 with the eight-core Core 3 N355 and the ASL051-BCD-N150 with the quad-core N150, both Twin Lake, plus the ASL051-BCD-N305 with the eight-core Core i3-N305 and the ASL051-BCD-N97 with the quad-core N97, both Alder Lake-N. TDPs run from 6 W on the N150 to 15 W on the N355 and i3-N305.

The I/O is the same across the range. Two 2.5GbE ports on Intel I226V controllers, two USB 3.2 Gen 2 Type-A ports, and internal headers for two USB 2.0 ports, two RS-232/422/485 ports and 8-bit DIO cover networks, peripherals and field signals. Three M.2 sockets handle expansion: an E-key 2230 for Wi-Fi and Bluetooth, a B-key 3042/2242 with a nano SIM slot for 4G or 5G, and a B-key 2242 on PCIe x2 or SATA for storage. A discrete TPM 2.0, CM9825 audio and a watchdog timer are fitted.

ASL051 boards run from 12 V DC on a terminal block and carry CE, FCC, UKCA and RoHS compliance. Supported operating systems are Windows 10 IoT Enterprise LTSC 2021, Windows 11 IoT Enterprise LTSC 24H2 and Linux, which suits OEMs maintaining one image across a product line.
