The NeoPixel Stick from Adafruit is a compact, chainable board featuring eight 5050 WS2812 RGB LEDs, each with an integrated driver chip for full individual addressability. With a constant current draw of about 18mA per LED, colors remain bright and consistent even with minor voltage fluctuations. The stick operates at 5V and communicates over a single data line using a timing-specific protocol, requiring a real-time microcontroller running at 8 MHz or faster (e.g., Arduino, AVR, PIC, mbed).
For easy integration, the board includes solder pads for wiring or breadboard use, along with two mounting holes for secure installation on various surfaces..
