DESCRIPTION
The SparkFun Qwiic LED Stick features ten addressable APA102 LEDs, making it easy to add full-colour 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 to. They have written an Arduino library and Python package that takes care of the I2C and communication to the LEDs so all you have to do is decide what colour 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 up to 100 LEDs (10 Qwiic LED Sticks) on a single bus! The address can also be changed to 0x22 by closing the solder jumper on the back of the board.
This board like many of the other Qwiic compatible boards is plug and go. No soldering, no figuring out which is SDA or SCL, and no voltage regulation or translation required!
Please Note:
- Using lots of LEDs can draw a lot of current. Make sure to consider the power limits of your setup. If you expect your LED chain to draw more than 600mA of current, connect your external supply directly to VLED. Closing the jumper from VLED to VCC will add a 4.7uF decoupling capacitor.
