SparkFun Qwiic Navigation Switch

The SparkFun Qwiic Navigation Switch is a compact joystick-like device that integrates seamlessly into your I2C bus, providing a versatile 5-way tactile switch for enhanced user input. It features a built-in RGB status LED for visual feedback and connects effortlessly using the Qwiic system, eliminating the need for soldering. The PCA9554 8-bit I2C I/O expander reads the switch inputs, and the board supports multiple daisy-chained connections with configurable I2C addresses.

This navigation switch is perfect for applications where additional input is needed. Whether you're navigating a menu or controlling a small robot, the tactile feedback from the 5-way switch offers precise control. The RGB LED provides immediate visual feedback, making it ideal for interactive projects.

One of the standout features is its ease of integration. With no soldering required, the Qwiic system allows for quick and straightforward connections. However, for those who prefer traditional methods, 2.54 mm spaced pins are available for breadboard use. The interrupt pin is also a handy feature, notifying the microcontroller of any state changes instantly.

For developers, SparkFun provides a basic example in their GitHub Hardware repository. The SparkFun I2C Expander Arduino Library is required to interact with the PCA9554's I/O pins, and it's easily accessible through the Arduino library manager or directly from GitHub. This makes it simple to get started and integrate the navigation switch into your projects.
