The board as it appears on the Velxio canvas, with its full pin map
read live from the simulator (regenerated by scripts/gen-boards.mjs,
so it always matches what you can wire).

About this board
Section titled “About this board”The same ATmega328P at 16 MHz as the UNO, 32 KB of flash, in a breadboard-friendly stick. Sketches move between the two without changes.
The one real difference is in the pin map below: the Nano exposes A6 and
A7, two extra analog-only inputs the UNO does not have. They read with
analogRead() but cannot be used as digital pins.
