DFI TWLF51 Intel Twin Lake and Amston Lake Femto-ITX Single Board Computers with 8GB LPDDR5 Memory Down

Where a board has to fit inside a sensor housing, a small gateway or a device with no room for a memory socket, every millimeter counts. The DFI TWLF51 series puts an Intel x86 processor, memory, storage and I/O on an 84 x 55 mm 1.8″ Femto-ITX board, so the finished design needs little more than a 12 V supply and its own enclosure.

Memory and storage are soldered: 8 GB of LPDDR5 at 4800 MHz and 64 GB of eMMC on every TWLF51 board, which means no socketed parts to fit or retain in vibration-prone equipment and a low board profile. Intel UHD Graphics drives an HDMI 2.0 output on a micro HDMI connector at up to 4096 x 2160 at 60 Hz, with hardware decode of HEVC, VP9, AV1 and AVC. A passive heatsink cools the board, and a discrete TPM 2.0 and watchdog timer are fitted.

Seven builds split into two temperature grades. The standard builds operate from -5 to 65 °C: the TWLF51-BT-86N35 with the eight-core Intel Core 3 N355 at 15 W and the TWLF51-BT-86N15 with the quad-core Intel N150 at 6 W, both Twin Lake, and the TWLF51-BT-86N10 with the quad-core Intel N100 (Alder Lake-N) at 6 W. The Amston Lake builds operate from -20 to 70 °C: the TWLF51-EC-86X78 with the eight-core Atom x7835RE at 12 W, the TWLF51-EC-86X74 with the quad-core Atom x7433RE at 9 W, and two dual-core options, the TWLF51-EC-86X72 with the Atom x7211RE at 6 W and the TWLF51-EC-86X7213RE with the Atom x7213RE at 9 W and a higher 2.0 GHz base clock.

The I/O is lean but covers a typical controller: one GbE port on an Intel I210-IT controller, two USB 3.2 Gen 2 Type-A ports on the rear edge, two USB 2.0 ports and one RS-232/422/485 port on internal headers, and 8-bit digital I/O for sensors and relays. An M.2 E-key 2230 socket on PCIe Gen3 x1 and USB 2.0 takes a Wi-Fi and Bluetooth module.

Every TWLF51 board runs from 12 V DC on a terminal block, supports Windows 11 IoT Enterprise and Linux, and carries CE, FCC, UKCA and RoHS compliance. The -20 to 70 °C Atom builds can suit unheated cabinets, lobby kiosks and transport equipment, while the -5 to 65 °C builds suit devices installed indoors.
