The SparkFun Differential I2C Breakout is the fastest and easiest way to extend the range of your I2C communication bus. The breakout uses NXP’s PCA9615 IC, which converts the two default I2C signals into four differential signals, two for SCL and two for SDA. The differential signals are sent over an Ethernet cable, which attaches to the breakout through the on-board RJ-45 connectors. The differential signalling allows the I2C signals to reach distances of up to 100ft. while still maintaining their signal integrity! To make it even easier to get your readings, all communication is enacted exclusively via I2C, utilising the handy Qwiic system so no soldering is required to connect it to the rest of your system. However, there is still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

The simplicity of the Differential I2C Breakout is one of its biggest appeals. Other I2C communication methods require packetising I2C communication into another protocol, be it RS-485 or 1-Wire. However, the PCA9615 keeps the I2C protocol by utilising a differential transceiver.

Whether you need to extend the range of an I2C sensor on an autonomous vehicle plagued with noise from motors or want to create a vast sensor network in your home or office, the Qwiic Differential I2C Breakout is a great solution to extend distance and reduce noise susceptibility.

Extending an I2C connection

A pair of these devices did the job perfectly for me, and they were very simple to use. I plugged and played.

SparkFun Differential I2C Breakout

The product works exactly as specified on the website with a very good description (mostly) of what jumpers to cut and why. I did initially cut the pull up jumpers on both devices in a pair, whereas is turns out I only needed to cut the pull up jumpers on the device on the bus of the master I2C unit that already has pull up resistors in place. A quick and easy re-solder and it all worked.
