Feather Mainboard

Adafruit's Feather mainboard — the 51 by 23 mm board a project is built around, in whichever microcontroller and radio the job needs. Every one of them is the same footprint, the same four corner mounts and the same two header rows, so a shield fits any of them and swapping the board does not move anything else.
