The SparkFun Differential I2C¬†Breakout is the fastest and easiest way to extend the range of your I2C¬†communication bus. The breakout uses NXP‚Äôs 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.
