Arduino Nano

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).

Family: Arduino & AVR · Languages: Arduino C++

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.
