DFI TWLF51-EC-86X78 Intel Amston Lake Atom x7835RE Femto-ITX Single Board Computer with 8GB LPDDR5 Memory and -20 to 70 °C

Roadside cabinets, unheated plant rooms and transport equipment see temperatures that a standard board is not rated for, and the enclosures are often small. The TWLF51-EC-86X78 addresses both as the eight-core Amston Lake build of the DFI TWLF51 series, a 1.8″ Femto-ITX single board computer rated from -20 to 70 °C.

The Intel Atom x7835RE has eight cores clocked from 1.3 to 3.6 GHz at a 12 W TDP, enough to run protocol gateways, local logging and remote management side by side. DFI lists in-band ECC (IBECC) support for the Amston Lake builds. Memory is 8 GB of LPDDR5 at 4800 MHz soldered down, storage is 64 GB of eMMC, and Intel UHD Graphics drives HDMI 2.0 at up to 4096 x 2160 at 60 Hz.

With memory and storage soldered, there are fewer socketed parts to work loose when the board is mounted in equipment that vibrates. The board provides one GbE port on an Intel I210-IT controller and two USB 3.2 Gen 2 Type-A ports, plus two USB 2.0 ports, one RS-232/422/485 port and 8-bit DIO on internal headers for field devices and signals. An M.2 E-key 2230 socket takes Wi-Fi and Bluetooth.

The TWLF51-EC-86X78 runs from 12 V DC on a terminal block and operates from -20 to 70 °C. It supports Windows 11 IoT Enterprise and Linux, with a discrete TPM 2.0 and CE, FCC, UKCA and RoHS compliance. The TWLF51-EC-86X74 halves the core count to four at 9 W for lighter loads in the same temperature range, and the TWLF51-BT-86N35 offers eight Twin Lake cores at 15 W for indoor builds at -5 to 65 °C.
