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
