.. _bundle_installation:

Bundle

The bundles are available `on GitHub <https://github.com/adafruit/Adafruit_CircuitPython_Bundle/releases>`_.

To install them:

#. `Download <https://github.com/adafruit/Adafruit_CircuitPython_Bundle/releases>`_

and unzip the latest zip that's not a source zip.

#. Copy the ``lib`` folder to the ``CIRCUITPY`` or ``MICROPYTHON``.

Foundational

These libraries provide critical functionality to many of the drivers below. It

is recommended to always have them installed onto the CircuitPython file system in

the ``lib/`` directory. Some drivers may not work without them.
