DFI TWLF51-EC-86X72 Dual-Core Intel Atom x7211RE Femto-ITX Embedded Board with 8GB LPDDR5 Memory and -20 to 70 °C

A remote I/O node, a meter concentrator or a single-purpose controller often runs one small application for years, powered from a limited supply. The TWLF51-EC-86X72 is built for that kind of job: the 6 W dual-core member of the DFI TWLF51 series, a 1.8″ Femto-ITX embedded board rated from -20 to 70 °C.

The Intel Atom x7211RE has two cores running from 1.0 to 3.2 GHz within a 6 W TDP, the lowest of the Amston Lake builds, which keeps heat to a minimum in a small sealed enclosure. It works with 8 GB of LPDDR5 at 4800 MHz and 64 GB of eMMC, both soldered on, and DFI lists in-band ECC (IBECC) support for these Atom builds. Intel UHD Graphics drives HDMI 2.0 at up to 4096 x 2160 at 60 Hz if a local screen is needed.

The I/O suits a field device: one RS-232/422/485 port for Modbus or legacy instruments, 8-bit DIO for contacts and relays, and two USB 2.0 ports on internal headers. One GbE port on an Intel I210-IT controller links the node to the network, two USB 3.2 Gen 2 Type-A ports take service devices, and the M.2 E-key 2230 socket accepts a Wi-Fi and Bluetooth module.

The TWLF51-EC-86X72 runs from 12 V DC on a terminal block and operates from -20 to 70 °C, with Windows 11 IoT Enterprise or Linux, a discrete TPM 2.0 and CE, FCC, UKCA and RoHS compliance. The TWLF51-EC-86X7213RE keeps two cores but raises the base clock to 2.0 GHz at 9 W, and the TWLF51-EC-86X74 moves to four cores for heavier processing in the same range.
