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