SparkFun QwiicBus I2C Kit with EndPoints & Cables

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.

Technical Specifications

• I2C Supply Voltage: 2.3V–5.5V
• Differential Supply Voltage: 3V–5.5V
• Buck Regulator Supply Voltage (MidPoint): 3.6V–36V
