The two B2B connectors provide all MCU ports, power supplies and control-signals.
5.1 B2B Connectors (CN1, CN2)
These two connectors provide all signals to a plug-under board like the Multi-IO-Board. Signals
include all MCU ports as well as reset and power supplies from the SK-board.
Signals are always routed to these connectors, even if they are used on the SK-MB9EF120-002,-003
themselves. When using a signal on a plug-under board which is also connected to an on-board
peripheral or connector, it must be disconnected from the on-board resource by pulling the
corresponding jumper. Some signals can be disconnected separately, while other signals are
disconnected as a whole function-block.
Fitting mates for the other board are SAMTEC QTH type connectors.
