The SparkFun Qwiic Directional Pad adds a 5-way directional pad to your I²C bus! When connected to a microcontroller, press down on the directional pad (up, down, left, right, or center) to provide additional input for your application. The built-in RGB status LED provides visual feedback indicating which button is pressed.

Populated on the board is a low profile, 5-way directional pad. Each pad includes a momentary push button read by the PCA9554 8-bit I²C I/O expander and notifies the microcontroller when a button is pressed. 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, Sparkfun still have broken out 0.1"-spaced pins if you prefer a breadboard

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

We've written a basic example for the Qwiic Directional Pad 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 and output buttons. Add a Qwiic Directional Pad to your project when navigating a menu, or even add it to a small remote to control a robot!

The SparkFun Qwiic Connect System is an ecosystem of I²C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
