WS2812B strip: 150 addressable RGB LEDs
At a density of 30 LED/m, the 5 m WS2812B strip has 150 addressable RGB LEDs in total, and each LED has a built-in driver and lights in its own color from a palette of 16,777,216 colors. Each of the 3 primary colors has 256 brightness levels, so you set smooth transitions and light effects in software for each LED separately.
The strip has a power of 9 W/m, is powered with 5 V and has an IP65 protection rating. You control the whole chain with one digital pin of a microcontroller, e.g. an Arduino or the ESP32 with the ESP-WROOM-32 module, because data passes from LED to LED over a single wire.

How the WS2812B works: one data wire
The WS2812B LED combines a driver and 3 LED dies in one 5050 package. The first LED latches the first 24 bits of data and passes the rest through the DOUT output to the next LED. The built-in circuit reshapes the signal, so distortion does not build up along the strip.
Data flows at 800 kb/s, 24 bits per LED in the order green, red, blue. A break in the signal longer than 50 µs ends the frame. With a refresh rate of 30 times per second, one chain drives at least 1024 LEDs, and the distance between two LEDs can exceed 5 m without additional circuits.
Bit 0 and bit 1 differ in pulse length: one bit lasts 1.25 µs. A high state of 0.4 µs means zero, and 0.8 µs means one. The red die emits at a wavelength from 620 nm to 625 nm, the green from 522 nm to 525 nm and the blue from 465 nm to 467 nm.

| Pin | Function |

WS2812B signal timing
| Parameter | Time |
|---|---|
| Bit 0: high state T0H | 0.4 µs ±150 ns |
| Bit 0: low state T0L | 0.85 µs ±150 ns |
| Bit 1: high state T1H | 0.8 µs ±150 ns |
| Bit 1: low state T1L | 0.45 µs ±150 ns |
| Duration of one bit | 1.25 µs ±600 ns |
| Reset, end of frame | low state above 50 µs |
WS2812B with Arduino and ESP32
You connect the strip to a microcontroller with one data line, which you route to the DIN input of the first LED. A high state on the DIN input is at least 0.7 of the supply voltage, which is 3.5 V with a 5 V supply.
Arduino boards with 5 V logic drive the strip directly. A microcontroller with 3.3 V logic, e.g. the ESP32, outputs a signal below this threshold, so it is worth raising the data signal level to 5 V with a logic level shifter.

Is it a good choice for you?
A good choice if:
- you are building lighting with effects where each LED shines in a different color
- you control the strip from an Arduino or ESP32 with one data line
- you mount the strip in a place exposed to dust and water, where IP65 comes in handy
Consider another option if:
- you have a 12 V supply and do not want to add a 5 V converter
- you need an ordinary single-color strip without control of each LED
Fun fact
Colors in the order G, R, B
Although we talk about RGB LEDs, the WS2812B receives data in the order green, red, blue, starting from the most significant bit. Remember this byte order when you control the strip yourself.

Frequently asked questions
Does the WS2812B work on 12 V?
No. This strip is powered with 5 V, and the permitted supply voltage of the LED itself is from 3.5 V to 5.3 V.
How many LEDs does a 5 m strip have?
The strip has a density of 30 LEDs per meter, so a 5 m length has 150 addressable RGB LEDs, and you control each one separately.
How do I connect the WS2812B to an ESP32?
Route the signal from a GPIO pin to the DIN input of the first LED. The ESP32 works with 3.3 V logic, and an LED powered at 5 V requires at least 3.5 V, so raise the signal level to 5 V.
What power supply for a 5 m strip?
Choose a 5 V power supply rated at least 45 W, because the strip draws 9 W per meter. At 5 V this means a current of up to 9 A for the whole length.
