Active I2C Long Cable Extender P82B715 Module
This module is designed to enable long-range I2C communications which extend the cable length from several meters to about 50 meters. 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. Additionally, there are two LEDs that indicate the SCL and SDA activities on the bus. Both the LEDs are driven by transistors which draw negligibly small current from the SCL and SDA lines.
A fully tested Active I2C Bus Extender Module module
A 4-pin 30cm cable (with interlock connector on one end, free on the other)
