Hw-133-v1.0 Datasheet Today

Disclaimer: Always check the specific revision of your board. LEDs are sensitive to electrostatic discharge (ESD).

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 Disclaimer: Always check the specific revision of your board

void setup() { strip.begin(); strip.show(); // Initialize all pixels to 'off' strip.setBrightness(50); // 50% brightness to save power } This compact PCB hosts a circular array of WS2812B LEDs

Adafruit_NeoPixel strip = Adafruit_NeoPixel(NUM_LEDS, PIN, NEO_GRB + NEO_KHZ800);

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
