ECM-TGU
Series: ECM
Manufactured byAvalue
The Avalue ECM-TGU is a 3.5-inch Single Board Computer designed for industrial and embedded applications. It integrates 11th Gen Intel® Core™ i7/i5/i3 and Celeron® processors, supporting up to 32GB DDR4 3200MHz SO-DIMM memory. Key features include quad display outputs (2 x DP++, 1 x LVDS, 1 x eDP), triple Ethernet ports (1 x 2.5GbE, 2 x 1GbE), multiple USB ports, serial interfaces, GPIOs, and expansion options through M.2 Key-B, Key-E, and Key-M slots. With a compact form factor of 146mm x 101mm and support for Windows and Linux operating systems, the ECM-TGU offers a robust solution for space-constrained environments.
