| 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 |
