ECM-EHL
Series: ECM
Manufactured byAvalue
The Avalue ECM-EHL is a 3.5-inch Single Board Computer designed for industrial and embedded applications. It integrates Intel® Atom® x6000E and Celeron® processors, supporting up to 32GB DDR4 3200MHz SO-DIMM memory. Key features include triple display outputs (DP 1.4a, HDMI 2.0b, eDP 1.3), dual Ethernet ports (2.5GbE and 1GbE), multiple USB ports, serial interfaces, GPIOs, and expansion options through M.2 Key-B and Key-E slots. With a compact form factor of 146mm x 101mm and support for Windows and Linux operating systems, the ECM-EHL offers a robust solution for space-constrained environments.
