| GPIO pins exposed on Arduino Nano (R3) headers. |
| |
| The Arduino Nano layout provides two headers on opposite edges of the board. |
| |
| * A 15-pin header with mostly digital signals. The additional NRST (pin3) |
| and GND (pin 4) pins are not exposed by this binding. |
| * A 15-pin Analog Input and power supply header. This has analog input |
| signals labeled from A0 through A7, as well a digital signal D13. The |
| power supply and reset pins are not exposed by this binding. |
| |
| This binding provides a nexus mapping for 22 pins where parent pins 0 |
| through 13 correspond to D0 through D13, and parent pins 14 through 21 |
| correspond to A0 through A7, as depicted below. |
