The Qwiic LED Stick features ten addressable APA102 LEDs, making it easy to add full color LED control using I²C. Write to individual LEDs to display a count in binary, or write to the whole strip for cool lighting effects. You can even add more LEDs to the end if you need to¹. We’ve written an Arduino library that takes care of the I²C and communication to the LEDs so all you have to do is decide what color each LED should be.

The LED Stick has a default I²C address of 0x23 but can be changed with a simple command, allowing you to control over 100 Qwiic LED Sticks on a single bus¹! The address can also be changed to 0x22 by closing the solder jumper on the back of the board.

This board is one of our many Qwiic compatible boards! Simply plug and go. No soldering, no figuring out which is SDA or SCL, and no voltage regulation or translation required!

We do not plan to regularly produce SparkX products so get them while they’re hot!

Experimental Product: SparkX products are rapidly produced to bring you the most cutting edge technology as it becomes available. These products are tested but come with no guarantees. Live technical support is not available for SparkX products. Head on over to our forum for support or to ask a question.

1: Using a lot of LEDs can draw a lot of current. Make sure to consider the power limits of your setup. If adding an external power supply, cut the trace on the back of the board from VLED to 3.3V. If you expect more than 1A of current, connect your external supply directly to VLED. Closing the jumper from VLED to VCC will add a 4.7uF decoupling capacitor.
