SparkFun QwiicBus I2C EndPoint for I2C Bus Extension
Extend I2C bus range up to 100ft with SparkFun’s QwiicBus EndPoint. PCA9615 buffer, Qwiic-compatible, 2.3-5.5V support.
The SparkFun QwiicBus I2C EndPoint offers a straightforward yet powerful solution for extending your microcontroller's I2C bus range using standard Ethernet cables. This innovative device serves as both the start and endpoint for connections, ensuring signal integrity over distances of up to 100 feet.
Key Features
- PCA9615 Buffer IC: Converts I2C signals into four differential signals (2x SCL, 2x SDA) for compatibility and ease of use.
- Qwiic-Compatible: Designed to integrate seamlessly with the Qwiic system for effortless prototyping, featuring two Qwiic connectors for quick connections.
- Flexible Power Options: Supports I2C supply voltages from 2.3V to 5.5V and differential supply voltages from 3V to 5.5V.
- Breadboard-Friendly: Includes optional 0.1” pins, making it easy to prototype on standard breadboards.
Note: For optimal performance, two QwiicBus EndPoints must be used together—one at each end of your I2C bus extension.
Ideal for hobbyists, engineers, and developers looking to expand their I2C bus range while maintaining high signal quality, this compact and efficient solution simplifies long-distance I2C communications without complex wiring.
