SparkFun QwiicBus - EndPoint



Description Attachments

The SparkFun QwiicBus EndPoint is a quick and efficient solution for extending the range of your I2C communication bus. This device employs the PCA9615 IC from NXP to transform the standard I2C signals into four differential signals. With the help of an Ethernet cable connected via the built-in RJ-45 connectors, these differential signals can travel up to 30.48 meters while maintaining their integrity. The QwiicBus EndPoint exclusively uses I2C for communication, leveraging the Qwiic system to eliminate the need for soldering. For those who prefer using a breadboard, 2.54mm-spaced pins are available.

The QwiicBus EndPoint stands out for its simplicity. While other I2C communication methods necessitate the conversion of I2C communication into different protocols like RS-485 or 1-Wire, the PCA9615 maintains the I2C protocol by using a differential transceiver.

In the updated version of the Differential I2C Breakout, two 2.54mm-spaced pins are connected to the spare pair of wires on the RJ-45 connectors. This feature allows users to utilize the extra pair as they see fit.

The QwiicBus EndPoint is an ideal solution for those who need to extend the range of an I2C sensor on a noise-prone autonomous vehicle or those who wish to establish a large sensor network in a home or office. It offers an effective way to increase distance and reduce noise susceptibility.

The SparkFun Qwiic Connect System is a comprehensive ecosystem of I2C sensors, actuators, shields, and cables that simplifies prototyping and reduces the potential for errors. All Qwiic-enabled boards use a standard 1mm pitch, 4-pin JST connector, which minimizes the required PCB space. The polarized connections ensure a correct and error-free hookup.

Features of the SparkFun QwiicBus EndPoint include the use of the PCA9615 buffer IC, an I2C supply voltage range of 2.3-5.5V, a differential supply voltage range of 3-5.5V, and multiple power configurations to suit various application needs. It can extend the I2C bus up to 30.48 meters and has two Qwiic connectors.
