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.



• Multi-drop distribution of I2C-bus signals using low-cost twisted-pair cables

• Dual, bidirectional, unity voltage gain buffer with no external directional control required

• Compatible with I2C-bus and its derivatives SMBus, PMBus, DDC, etc.

• Supply voltage range 3V to 12V

• Clock speeds to at least 100 kHz and 400 kHz when other system delays permit

• 4-pin interlock connectors onboard

• 4-pin interlock cables included in the package

• Compact size
