Higher level NeoPixel driver that presents the strip as a sequence. This is a supercharged version of the original MicroPython driver. Its now more like a normal Python sequence and features slice support,


Colors are stored as tuples by default. However, you can also use int hex syntax to set values similar to colors on the web. For example,

on the web) is equivalent to
(0x10, 0, 0)

.. note:: The int hex API represents the brightness of the white pixel when present by setting the RGB channels to identical values. For example, full white is 0xffffff but is actually (0, 0, 0, 0xff) in the tuple syntax. Setting a pixel value with an int will use the white pixel if the RGB channels are identical. For full, independent, control of each color component use the tuple syntax.


This driver depends on:

  • Adafruit CircuitPython 

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading

the Adafruit library and driver bundle 

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally

_. To install for current user:

.. code-block:: shell

pip3 install adafruit-circuitpython-neopixel

To install system-wide (this may be required in some cases):

.. code-block:: shell

sudo pip3 install adafruit-circuitpython-neopixel

To install in a virtual environment in your current project:

.. code-block:: shell

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-neopixel

Usage Example

This example demonstrates the library with the single built-in NeoPixel on the

Feather M0 Express 
_ and
Metro M0 Express 

.. code-block:: python

import board
import neopixel

pixels = neopixel.NeoPixel(board.NEOPIXEL, 1) pixels[0] = (10, 0, 0)

This example demonstrates the library with the ten built-in NeoPixels on the

Circuit Playground Express 
. It turns off ``autowrite
so that all pixels are updated at once when the
show`` method is called.

.. code-block:: python

import board
import neopixel

pixels = neopixel.NeoPixel(board.NEOPIXEL, 10, auto_write=False) pixels[0] = (10, 0, 0) pixels[9] = (0, 10, 0)

This example demonstrates using a single NeoPixel tied to a GPIO pin and with a

to specify the color channel order. Note that
does not need to be specified as it is computed from the supplied

.. code-block:: python

import board
import neopixel

pixel = neopixel.NeoPixel(board.D0, 1, pixel_order=neopixel.RGBW) pixel[0] = (30, 0, 20, 10)
