WS2811 LED Driver Chip (10-pack)
Overview
The WS2811 is a dedicated 3-channel LED driver IC designed for controlling RGB LEDs using a single-wire digital interface. Each chip provides 8-bit PWM control for each channel, allowing for 24-bit color depth per pixel when cascaded in a series. This DIP8 package version is specifically designed for easy integration into breadboards and through-hole PCB designs.
Why Choose This Part
The WS2811 features a built-in signal reshaping circuit that prevents signal distortion from accumulating across long cascaded chains. Its single-line transmission protocol simplifies PCB routing and reduces the GPIO count required from the host controller. The integrated power-on reset and electric reset circuits ensure predictable startup behavior and data integrity.
Applications
Getting Started
To use these chips, connect the VDD pin to a 5V power source and the GND pin to your system ground. Use a microcontroller like an Arduino or ESP32 with the FastLED or NeoPixel library to send data to the DIN pin. Because these are in DIP8 packages, they can be plugged directly into a breadboard for rapid prototyping before soldering to a permanent PCB.
