FACE Modules Documentation
Concept
FACE Module (Function And Connectivity Extension Module) designed as additional/optional system board providing extended functionality and IO connectivity options. The interface between main system board and FACE module implemented with high speed, low pitch, and high pin count board-to-board connectors (B2B). Connectors’ pinout including signals mapping and description described later in this chapter.
