I2C

I2C is a synchronous, multi-master, multi-slave communication bus intended for lower-speed peripheral connections on a circuit board.

The I2C XB is a hardware implementation of the I2C protocol which supports all of the standard Arduino I2C (Wire) functions. The I2C XB provides the option to add hardware I2C ports to an Alorium board.

Adding another I2C interface can be useful especially in a prototyping environment where driving multiple slaves on a single I2C bus may be impractical.
