adafruit-feather-header

Vendor: Generic or vendor-independent

Description

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
