DFI ASL051-TTD-x7211RE Intel Amston Lake Atom x7211RE Pico-ITX Board with Dual 2.5GbE and -40 to 85 °C

Remote telemetry units, substation gateways and simple machine controllers are often powered from limited supplies and sealed inside small enclosures, so heat and power draw decide the processor. The ASL051-TTD-x7211RE is the 6 W build of the DFI ASL051 series, a 2.5″ Pico-ITX board rated from -40 to 85 °C.

Its Intel Atom x7211RE is an Amston Lake processor with two cores running from 1.0 to 3.2 GHz at a 6 W TDP, the lowest in the series alongside the N150. That is typically enough for protocol conversion, data logging and a web-based configuration interface. Memory is a single DDR5 SO-DIMM socket at 4800 MHz, taking up to 16 GB, and Intel UHD Graphics can drive a local HMI.

Two RS-232/422/485 ports and 8-bit DIO on internal headers handle Modbus devices, alarms and relays, and two 2.5GbE ports on Intel I226V controllers give separate uplink and field networks. Two USB 3.2 Gen 2 Type-A ports and two internal USB 2.0 ports take service tools or peripherals. HDMI and dual-channel LVDS remain available for a display, and three M.2 sockets add Wi-Fi, 4G or 5G with a nano SIM, and SSD storage.

The ASL051-TTD-x7211RE runs from 12 V DC on a terminal block, with CE, FCC, UKCA and RoHS compliance, a discrete TPM 2.0 and a watchdog timer, and supports Windows 10 and 11 IoT Enterprise LTSC and Linux. The ASL051-TTD-x7433RE doubles the cores to four at 9 W in the same temperature range, and the ASL051-BCD-N150 offers four cores at 6 W for indoor builds at -5 to 65 °C.
