PoNetI2Cextender

I2C extender PoNetI2Cextender is an I2C line buffer and signal conditioner.

I2C extender provides 10 times higher line drive than standard I2C thus improving data integrity. Up to 25m – 50m long I2C line with CAT3 or better twisted pair cable is possible, compared to few tenths of am without I2C extender. Besides 10 times higher line drive, it can also improve signal integrity in a noisy environment.

PoNetI2Cextender can transfer I2C data over longer lines for almost every I2C device

PoNetI2Cextender can guarantee reliable operation on longer I2C lines between any I2C devices including PoKeys57U, PoSensors2, PoNETkbd48 CNC keyboard, and others. Signal tests with more than 100 different I2C ICs guarantee reliability.

There are 330-ohm pull-up resistors installed on the PCB what is usually enough for reliable operation. However, for operation in the longest lines and/or noise environment, additional 470-ohm pull-ups can be mounted externally.

To extend the I2C connection, two I2C extenders must be used with one on each side of the extension cable.

Features:

  • up to 50m I2C line when using CAT3 or better-twisted pair cable
  • compatible with 100 kHz and 400 kHz I2C
  • simple 4 pin flat cable connection between extenders
  • 5 pin PoNET or 10 pin PoExtension connector for connection to PoKeys, Arduino, Raspberry Pi, or another device
  • 4,5V – 12V power supply only
  • 3V operation possible with reduced performance
  • less than 25 mA supply current

In the package:

  • fully tested I2C extender module (single device in the package for a single I2C device, you need a minimum 2 of them)
  • 5 pin PoNET cable with connectors on both sides
  • 6 pin MicroMaTch connector for flat cable for I2C line extension

Units must be ordered in pairs. One for each side of the long I2C cable.
