Overview
Ai03 tutorial is an open-source printed circuit board by benoittgt, from the benoittgt/ai03_tutorial repository on GitHub, published under the MIT licence. It is a 2-layer board with 25 parts on 21 nets, routed with 220 tracks and 7 vias.
It is built around the ATMEGA32U4-AU. Its parts include 7 capacitors, 4 resistors, 4 diodes, 1 IC and 1 switch. It belongs with the AVR (ATmega, ATtiny) boards of this library.

⚠️ This is a prototype that has not been builded for the moment. I am waiting for review ⚠️
Thanks ai03 and Ruiqi Mao for this very good guide (baby steps, shortcuts, many screenshots, electronic tips...).
Feedbacks for the original guide
Part 4
- Hard to find all schema. I had to import one by one lib from https://github.com/ldoiron17/Kicad_Libraries
- Different menu: "Switch to inch instead of mm on the left pane, and open Setup -> Design Rules." is Board Setup -> Design Rules -> Net classes
- Different menu: "Then click on the first corner of the zone to surround to bring up a menu." the "Copper Zone Properties" is different
Part 6
- Copper Zone Properties doesn't offer "Boundary mode" anymore
- When I try to simulate the board it's not delimited by the line
- When I run the DRC the Molex connector have unclosed path so I need to switch
- DRC told be that "Driled holes too close together" for MX-1U

Questions
What parts does the Ai03 tutorial use?
25 parts, built around the ATMEGA32U4-AU. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Ai03 tutorial KiCad files?
From the benoittgt/ai03_tutorial repository on GitHub, at the commit this page was made from: the board is ai03_tutorial/ai03_tutorial.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ai03 tutorial design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
