DFI TWLF51-BT-86N35 Intel Core 3 N355 1.8″ Femto-ITX SBC with 8GB LPDDR5 Memory and 64GB eMMC

Edge gateways that run protocol conversion, a local database and a web dashboard at the same time benefit from more cores even when the enclosure is palm-sized. The TWLF51-BT-86N35 brings eight cores to the 84 x 55 mm footprint of the DFI TWLF51 series, as a 1.8″ Femto-ITX SBC for integration into an OEM housing.

Its Intel Core 3 N355 is a Twin Lake processor with eight cores at 15 W TDP, clocked from 1.8 to 3.9 GHz, which makes it the fastest build in the series. Memory is 8 GB of LPDDR5 at 4800 MHz soldered to the board, and 64 GB of eMMC holds the operating system and application. Intel UHD Graphics drives HDMI 2.0 at up to 4096 x 2160 at 60 Hz and decodes HEVC, VP9, AV1 and AVC in hardware.

I/O is sized for a controller or gateway: 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. The HDMI output uses a micro HDMI connector to save edge space. An M.2 E-key 2230 socket takes a Wi-Fi and Bluetooth module where the design needs wireless.

The TWLF51-BT-86N35 runs from 12 V DC on a terminal block, cools passively through its heatsink and operates from -5 to 65 °C, so it suits equipment installed indoors. Windows 11 IoT Enterprise and Linux are supported, with a discrete TPM 2.0 and CE, FCC, UKCA and RoHS compliance. For -20 to 70 °C operation with eight cores, the TWLF51-EC-86X78 uses the Atom x7835RE at 12 W, and the TWLF51-BT-86N15 offers four cores at 6 W for lower-power builds.
