ECM-SKLU
Series: ECM
The Avalue ECM-SKLU is a 3.5-inch Single Board Computer designed for industrial and embedded applications. It integrates 6th Gen Intel® Core™ i7/i5/i3 BGA processors, supporting up to 16GB DDR4 2133MHz SO-DIMM memory. Key features include triple display outputs (2 x HDMI, 1 x LVDS), dual Gigabit LAN ports (Intel® I211AT and I219LM), multiple USB ports (4 x USB 3.0, 2 x USB 2.0), serial interfaces (1 x RS-232/422/485, 5 x RS-232), GPIOs, and expansion options through M.2 (2242) B-Key and Mini PCIe slots. With a compact form factor of 146mm x 101mm, wide voltage input range of 12V to 24V DC, and support for Windows and Linux operating systems, the ECM-SKLU offers a robust solution for space-constrained environments.
