arduino-nano-header-r3

Vendor: Generic or vendor-independent

Description

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.
