================================================================================
Use Adafruit TrellisM4 Express board as 2 Neotrellis seesaw boards with CircuitPython.
You can you use this to extend TrellisM4 with Neotrellis (seesaw) boards.
* Author(s): arofarn
Implementation Notes
--------------------
**Hardware:**
* Adafruit NeoTrellis M4 Express: https://www.adafruit.com/product/3938
**Software and Dependencies:**
* Adafruit CircuitPython firmware for the supported boards:
