Description
***********



.. code-block:: none

   GPIO pins exposed on Adafruit Feather headers.

   The Feather layout provides two headers, one each along
   opposite edges of the board.
   Proceeding counter-clockwise:
   * A 16-pin header.  12 pins on this header are exposed
     by this binding.
   * A 12-pin header.  9 pins on this header are exposed
     by this binding.

   This binding provides a nexus mapping for 21 pins where parent pins 0
   through 5 correspond to A0 through A5, and parent pins 6 through 20
   correspond as depicted below:

       - RESET
       - 3V3
       - 3V3
       - GND
       0 A0                     - VBAT
       1 A1                     - EN
       2 A2                     - VBUS
       3 A3                     D13  20
       4 A4                     D12  19
       5 A5                     D11  18
       6 SCK                    D10  17
       7 MOSI                   D9   16
       8 MISO                   D6   15
       9 RX                     D5   14
      10 TX                     SCL  13
      11 D4                     SDA  12
