Description
The DFI TWLF51 is a compact and highly efficient 1.8″ industrial single board computer, purpose-built for embedded and space-constrained applications. Designed around Intel’s latest Atom X Series and N Series processors (Amston Lake / Twin Lake), it delivers reliable performance and power efficiency for edge computing, automation, and IoT deployments. With its ultra-small 1.8″ form factor, the TWLF51 is ideal for integration into systems where space is at a premium, without compromising on functionality. It features onboard LPDDR5 memory with up to 8GB capacity, providing fast data processing and improved system responsiveness for demanding embedded workloads.
Despite its size, the board offers flexible expansion via an M.2 E Key slot, with optional I2C/SMBus support, enabling easy integration of wireless modules and additional functionality. A rich selection of I/O interfaces ensures seamless connectivity, including Intel Gigabit Ethernet, multiple USB ports, COM support, and digital I/O for industrial control applications. For display capabilities, the TWLF51 includes HDMI 2.0 with support for resolutions up to 4K at 60Hz, making it suitable for high-quality visual output in applications such as digital signage, HMI systems, and monitoring solutions.
Combining compact design, modern connectivity, and reliable performance, the DFI TWLF51 is an excellent solution for developers and system integrators building next-generation embedded and industrial systems.
