18)SMBus Connector (5-1 pin SMB)

This connector allows you to connect SMBus (System Management Bus) de- vices. SMBus devices communicate by means of the SMBus with an SMBus host and/or other SMBus devices. SMBus is a specific implementation of an I2C bus, which is a multi-device bus; that is, multiple chips can be connected to the same bus and each one can act as a master by initiating data transfer.
