SparkFun QwiicBus – MidPoint

SparkFun QwiicBus – MidPoint works with the QwiicBus Endpoint to extend the range of an I²C bus and easily tap into drop-in devices. The QwiicBus uses the NXP PCA9615 IC that converts the two default I²C signals into four differential signals, two for SCL and two for SDA. The differential signals sent over Ethernet cables from the EndPoint connect to the breakout through the onboard RJ-45 connectors. The differential signaling allows the I²C signals to reach distances of up to 100-ft. while maintaining signal integrity.
