Trying to make a keyboard PCB

I followed the guide of ai03, can find in the following link https://wiki.ai03.com/books/pcb-design/chapter/pcb-designer-guide

Note: In the KiCad rules check it throws me some errors but are about the footprints so i decided to ignore they, i dont really know if the PCB works

Keyboard pcb tutorial: common questions

What microcontroller does the Keyboard pcb tutorial use?

The Keyboard pcb tutorial is built around the ATmega32U4-A, from the AVR/Arduino family.

How big is the Keyboard pcb tutorial?

The Keyboard pcb tutorial measures 79.4 × 38.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Keyboard pcb tutorial?

24 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Keyboard pcb tutorial design files?

From the JavierEduardoRomeroTellez/keyboard-pcb-tutorial repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Keyboard pcb tutorial design in my own project?

Yes, under the terms of its MIT license, which JavierEduardoRomeroTellez chose for the repository.

Can I test firmware for the Keyboard pcb tutorial without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
