`adafruit_pybadger.pybadge`
================================================================================

Badge-focused CircuitPython helper library for PyBadge, PyBadge LC and EdgeBadge.
All three boards are included in this module as there is no difference in the
CircuitPython builds at this time, and therefore no way to differentiate
the boards from within CircuitPython.


* Author(s): Kattni Rembor

Implementation Notes
--------------------

**Hardware:**

* `Adafruit PyBadge <https://www.adafruit.com/product/4200>`_
* `Adafruit PyBadge LC <https://www.adafruit.com/product/3939>`_
* `Adafruit EdgeBadge <https://www.adafruit.com/product/4400>`_

**Software and Dependencies:**

* Adafruit CircuitPython firmware for the supported boards:
  https://github.com/adafruit/circuitpython/releases
