I made this schematic for the Arduino Nano 3.2 to be as close as possible to the official schematic found here. I chose similar components as on the official Nano. This does mean the schematic is a bit weird, as the resistors, for example, are merged into resistor arrays, meaning I had to make some jumps to the arrays. The PCB dimensions and the headers should be accurate enough to make measurements for a housing or Nano compatible board (provided as-is though), however, most measurements with component placement have been eyeballed. I also didn't map the traces, so some identical components might be swapped from their actual place on the board. I needed the schematic for a project, and thought I might as well share.

To be clear, I am in no way affiliated with Arduino.

The schematic is a direct copy of the one provided by Arduino themselves, so it should be exactly the same as the schematic used in the production of the real deal. I'm pretty sure the schematic is a 1:1 copy, but you should probably still check it yourself (just good practice really).
My reference is here:

Does the schematic work?
I am making a board with this as a template and don't know if i will be good using this.
Thank you very much for publicizing this and all your work  you have done!
