**CircuitPython** is a *beginner friendly*, open source version of Python for tiny, inexpensive
computers called microcontrollers.

This package contains the "stubs", or type definitions for CircuitPython.  With some advanced
editors and other tools, this information can be identify TypeErrors, AttributeErrors, and other
problems before you deploy your code to a device and can even help autocomplete your code.
