The RadiSys EXP-BP2 is an L-shaped subplane module that provides essential signal routing and connectivity within VMEbus embedded systems. It interfaces with the VMEbus backplane via a P2 connector and supports a processor and up to two EXM (Expansion Module) units through dedicated connectors designated as EXM slot 0 (lower) and slot 1 (upper). The module integrates peripheral expansion capability into demanding industrial computing and embedded applications.
