{"title":"WS2811 NeoPixel LED Driver Chip - 10 Pack","handle":"ws2811-neopixel-led-driver-chip-10-pack","url":"/products/ws2811-neopixel-led-driver-chip-10-pack","description":"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.\n\nThe 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.\n\nKey Features\n\n\nWS2811 Driver IC – The same chip used in NeoPixel products\n\nConstant Current Output – ~18 mA per channel, no resistors needed\n\nChainable – Connect data out to data in for long LED strings\n\nDual Speed – Supports 400 kHz and 800 kHz data rates\n\nSOIC-8 Package – Compact surface-mount, relatively easy to hand solder\n\nCommon-Anode Only – NPN transistor outputs, not compatible with common-cathode LEDs\n\n\nSpecifications\n\n\nPackage – SOIC-8\n\nOutput Current – ~18 mA per channel (constant current)\n\nData Rates – 400 kHz / 800 kHz\n\nMinimum Processor Speed – 4 MHz (at 400 kHz data rate)\n\nQuantity – 10 per pack\n\n\nIdeal For\n\nCustom addressable LED projects\nBuilding your own NeoPixel-compatible strips\nLED art installations and wearables\nArduino and microcontroller lighting projects\n\n\n\nNote: The WS2811 protocol requires precise timing and a real-time microcontroller (e.g. AVR, Arduino, ARM Cortex). It is not compatible with interpreted platforms or Linux-based single-board computers without dedicated hardware support.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":7704,"title":"Default Title","sku":"AF-1378","price":9.65,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
