SparkFun QwiicBus - EndPoint-Extends I2C Bus up to 100 feet-Maintain Signal Integrity-2x Qwiic Connectors-Supply Voltage Range 2.5-5.5V - Multiple Power configurations depending on Application Needs

Specifications:

The EndPoint acts as the starting and ending points of the QwiicBus and the MidPoint allows you to add a drop-in I2C connection to your long-distance differential I2C chain wherever you would like.
Uses the PCA9615 buffer IC; I2C Supply voltage range: 2.3-5.5V; Differential Supply voltage range: 3-5.5V; Multiple power configurations depending on application needs; Extends I2C bus up to 100 feet; 2x Qwiic Connectors
Using NXP's PCA9615 differential I2C bus buffer IC, the QwiicBus 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 EndPoint or MidPoint through the on-board RJ-45 connectors.
Differential signaling allows the I2C signals to reach distances of over 100 feet while still maintaining their signal integrity.
In our testing using two EndPoints, four MidPoints, at least one Qwiic device on each node and over 200 feet of Ethernet cable, we were able to use all devices with nearly no signal integrity loss!
