This small SOIC-8 chip drives RGB or single-color LEDs, similar to the one used in NeoPixel strips. It offers a constant current output of ~18mA per channel, ensuring consistent color regardless of voltage fluctuations. The chip is chainable, and requires a real-time microcontroller for communication, such as Arduino or AVR. It supports two speeds (400KHz and 800KHz). Ideal for creating custom smart LEDs, it simplifies your design without needing choke resistors. It works with Arduino's NeoPixel library but requires a 4MHz or faster processor.
