19) 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 I
2 C
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.
