QwiicBus - MidPoint
The SparkFun QwiicBus MidPoint 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 signaling allows the I2C signals to reach distances of up to 30 m while still maintaining their signal integrity.
