Introduction

The Baseboard supports COM Express Type 7 modules. The board breaks out major communications and peripheral interfaces as defined by the COM Express standard. It features front panel connectors for cable interfaces and a backplane edge connector designed for integrating the board into larger systems.

One of the supported COM Express Type 7 modules is the SolidRun LX2160A. It features 16 Arm Cortex-A72 processors, 4 x 10GbE and 18x PCIe Gen 3.0 lanes and is fully supported by Linux.

The board design files were created in KiCad 8.x. You can find out more about the COM Express 7 Baseboard by visiting Antmicro’s portals listed below:

They provide 3D renders and the board stackup definition, as well as an interactive preview of the board schematic. A PDF schematic of the board is also available.
