SparkFun QwiicBus I2C Kit with EndPoints & Cables
Extend I2C bus up to 100ft with the SparkFun QwiicBus kit. Includes EndPoints, MidPoint & cables for easy expansion.
The SparkFun QwiicBus I2C Kit provides a simple and efficient solution for extending I2C bus range in microcontroller projects using standard Ethernet cables. This kit includes two EndPoints, one MidPoint, and two Ethernet cables to help you get started quickly.
Key Features
The kit features the PCA9615 buffer IC, which converts I2C signals into four differential signals (2x SCL, 2x SDA) for improved signal integrity over long distances. With standard Ethernet cables, you can achieve a transmission range of up to 100 feet while maintaining robust signal quality.
Flexible Configurations
Create multiple configurations by adding more EndPoints and MidPoints to suit your project needs. The QwiicBus system is built around the user-friendly Qwiic connector system, ensuring easy plug-and-play connections. For those who prefer breadboarding, optional 0.1-inch header pins are available.
