(Mainboard Dimension Diagram Back)Product Overview
The MCD-LP49 is a domestically controllable, fully domestic COM-Express module that adheres to the PICMG COM.0 R2.1 Basic standard, with pin definitions compatible with COM Express Type 6. The module’s processor uses the Loongson LS3A3000 quad-core processor, with a maximum frequency of 1.5GHz (standard configuration at 1.2GHz), equipped with the second-generation domestically produced bridge chip 7A1000, and inter-chip communication utilizes the HT3.0 high-speed bus. This mainboard provides a rich set of interface resources, including commonly used interfaces such as PCIe, SATA, USB, UART, LVDS, and VGA.
The module features a high shock resistance, fully surface-mounted, modular design, characterized by high performance, high localization, high stability, and high reliability, making it suitable for a wide range of applications in government, scientific research, medical, power, communications, transportation, and other fields.
