DFI ASL051-TTD-x7433RE Quad-Core Intel Atom x7433RE Pico-ITX Single Board Computer with Dual 2.5GbE and -40 to 85 °C

Outdoor HMIs, EV charger displays and trackside controllers need a board that starts at -40 °C and keeps running at 85 °C, but most of them run one application with a display and a few field connections. The ASL051-TTD-x7433RE is the quad-core Amston Lake option in the DFI ASL051 series, a 2.5″ Pico-ITX single board computer for that kind of build.

The Intel Atom x7433RE runs four cores from 1.5 to 3.4 GHz at a 9 W TDP, a middle ground between the eight-core and dual-core builds that keeps thermal design straightforward. A DDR5 SO-DIMM socket supports up to 16 GB at 4800 MHz, and Intel UHD Graphics handles the HMI with hardware decode for HEVC, VP9, AV1 and AVC.

Dual-channel 18/24-bit LVDS drives a panel at up to 1920 x 1200 and HDMI adds a second display at up to 4096 x 2160 at 24 Hz. Two 2.5GbE ports on Intel I226V controllers connect to the site network and a local device network. Internal headers carry two RS-232/422/485 ports for meters or PLCs, 8-bit DIO and two USB 2.0 ports, with two USB 3.2 Gen 2 Type-A ports at the edge. M.2 sockets take Wi-Fi, 4G or 5G with a nano SIM, and SSD storage.

Power is 12 V DC through a terminal block, and the ASL051-TTD-x7433RE has CE, FCC, UKCA and RoHS compliance, a discrete TPM 2.0 and support for Windows 10 and 11 IoT Enterprise LTSC and Linux. If the software needs more threads in the same range, the ASL051-TTD-x7835RE offers eight cores at 12 W; for the lowest power, the ASL051-TTD-x7211RE runs two cores at 6 W.
