Interfaces

This section documents the board-level connectors and signals that are exposed on OpenNMC.

The OpenNMC exposes three groups of interfaces:

• SmartSlot-facing power and management signals
• external user-facing ports
• expansion signals brought out for add-on hardware

The board layout and the individual interface pages document the named signals and functional roles.
