WS2811 NeoPixel LED Driver Chip - 10 Pack

WS2811 SOIC-8 LED driver IC; drives one common-anode RGB LED or three individual LEDs at ~18mA constant current per channel (NPN outputs — incompatible with common-cathode). Chainable via single data line using a timing-sensitive protocol requiring a real-time microcontroller.
