ECM-CFS

Series: ECM

Manufactured byAvalue
ECM-CFS Front

The Avalue ECM-CFS is a 3.5-inch Single Board Computer designed for industrial and embedded applications. It integrates 8th/9th Gen Intel® Core™ i7/i5/i3, Pentium®, and Celeron® processors, supporting up to 32GB DDR4 2666MHz SO-DIMM memory. Key features include triple display outputs (2 x HDMI, 1 x LVDS), dual Gigabit LAN ports, multiple USB ports (4 x USB 3.1, 2 x USB 2.0), serial interfaces, GPIOs, and expansion options through mSATA and Mini PCIe slots. With a compact form factor of 146mm x 101mm and support for Windows 10 and Linux operating systems, the ECM-CFS offers a robust solution for space-constrained environments.
