SparkFun Qwiic Navigation Switch

Add a 5-way joystick and RGB LED to your project with the Qwiic Navigation Switch! I2C communication and Qwiic connect make it simple.

The SparkFun Qwiic Navigation Switch adds a small, joystick-like 5-way tactile switch to your I²C bus! When connected to a microcontroller, push the 5-way tactile switch toward a direction (up, down, left, right, or centre) to provide additional input for your application. The built-in RGB status LED provides visual feedback indicating when a switch is pushed.

Populated on the board is a 5-way tactile switch. Each direction includes a momentary switch that is read by the PCA9554 8-bit I²C I/O expander and notifies the microcontroller when a switch is pushed. The microcontroller will then provide visual feedback by writing to the non-addressable RGB LED. Each channel of the RGB LED can be disconnected from the PCA9554’s GPIO and connected to a different input. An interrupt pin is also broken out to notify your microcontroller when a state has changed quickly. We’ve also included an LED for power. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1′-spaced pins if you prefer a breadboard.

If you need multiple Qwiic Navigation Switches for your project, fear not! Each board has a configurable I²C address, so you can daisy-chain multiple Navigation Switches over Qwiic and address each individually.

We’ve written a basic example for the Qwiic Navigation Switch in our GitHub Hardware repository. You will need the SparkFun I2C Expander Arduino Library to read or write to the PCA9554’s eight separate I/O pins. You can download the library through the Arduino library manager by searching ‘SparkFun I²C Expander Arduino Library’, or you can get the GitHub repo as a .zip file and install the library from there.

This board is great for projects requiring additional input switches. Add a Qwiic Navigation Switch to your project when navigating a menu, or even add it to a small remote to control a robot!
