I2C BUS EXTENDER

This module is designed to enable long-range I2C communications which extend the cable length from few meters to about 50 meters this gives more flexibility in sensor placement in the field or away from the microcontroller unit.

Operating with any I2C master, slave or bus buffer is the primary advantage of this module. NXP P82B715 I2C bus extender IC is used as the main component of this module. 

The module has four pull-up resistors on board: two on the unbuffered bus side and another two on the buffered bus side.
