Description
For a development board with the basic features of the Feather MO range, plus a small prototyping area, try the Adafruit Feather Cortex-M0 Proto Board. It’s thin, lightweight, and easy to use for portable projects. In simple projects, where you would like to attach a button or sensor, you can skip on a breadboard and wire it directly on the board.
