WS2811 NeoPixel LED Driver Chip - 10 Pack
100 units available with a short lead time.
The WS2811 is the driver IC used in NeoPixel LED strips and pixels. In this SOIC-8 package, it lets you build your own addressable RGB LEDs by driving a single common-anode RGB LED or three individual single-colour LEDs. Each output provides ~18 mA constant current, ensuring consistent colour regardless of voltage variation — no current-limiting resistors required.
The chips are chainable by connecting the data output of one to the data input of the next, allowing long strings of individually addressable LEDs from a single data pin. The protocol supports both 400 kHz and 800 kHz data rates.
