If you are working on an Arduino, ESP32, or Raspberry Pi project that requires smooth, addressable RGB lighting, you have likely come across the HW-133-V1.0 . This compact PCB hosts a circular array of WS2812B LEDs. While the board is incredibly popular, finding a consolidated "datasheet" for the board itself (not just the chips) can be tricky. Here is everything you need to know. What is the HW-133-V1.0? Unlike a bare IC, the HW-133-V1.0 is a breakout board. It integrates WS2812B (or sometimes SK6812) LEDs onto a circular PCB with level-shifting and decoupling components. hw-133-v1.0 datasheet
#include <Adafruit_NeoPixel.h> #define PIN 6 #define NUM_LEDS 16 // Change to 8, 12, or 24 depending on your ring void setup() { strip
Disclaimer: Always check the specific revision of your board. LEDs are sensitive to electrostatic discharge (ESD). Here is everything you need to know
Since the HW-133-V1.0 is widely known as a breakout board (typically with 8, 12, 16, or 24 LEDs), the post is tailored to that specific component. Title: Deep Dive into the HW-133-V1.0 Datasheet: The Go-To RGB LED Ring
Adafruit_NeoPixel strip = Adafruit_NeoPixel(NUM_LEDS, PIN, NEO_GRB + NEO_KHZ800);
