Adafruit NeoPixel Ring - 16 x WS2812
Overview
This circular PCB features 16 individually addressable RGB LEDs integrated with WS2812 drivers. Each pixel is controlled via a single-wire digital protocol, allowing for full 24-bit color depth and brightness control for the entire ring using just one microcontroller pin.
Why Choose This Part
The integrated drivers allow for a chainable design that minimizes wiring complexity and PCB real estate. The timing-specific protocol is supported by extensive open-source libraries, ensuring compatibility across a wide range of 5V microcontrollers.
Applications
Getting Started
Connect the 5V and GND pins to a regulated power supply capable of handling peak current for 16 LEDs, then connect the Data Input pin to a microcontroller. Utilize the Adafruit NeoPixel library for Arduino or the CircuitPython NeoPixel module to begin controlling individual pixel colors.
