        # Leonardo

Arduino Leonardo schematic ported to Kicad

# Kicad 8

The design has been ported to Kicad 8.  

* DRC shows no error nor warning on PCB.

* All selected parts are easily availables.

* All parts contains 3 additional fields

    * Manufacturer containing the name of the manufacturer

    * Manufacturer_ref containing the part real reference

    * Digikey_ref containing a Digikey part number

NM, DNP parts are parts not mounted

# Why

Because I need to adapt the Leonardo design to include other functionalities my first work is to port the very good Arduino Leonardo rev3d to Kicad 6.  

# Crystal

16MHz Crystal is not yet selected…

# Schematic

[![Schematic](https://raw.githubusercontent.com/eltorio/leonardo/main/schematic.png)](https://github.com/eltorio/leonardo/raw/main/schematic.pdf?raw=true)

# Board

![Board](https://github.com/eltorio/leonardo/blob/main/board.png?raw=true)

The board is adapted and routed with the parts I have selected.  

Kicad 8 DRC check doesn't show any errors nor any warning.  

Component references are hidden by default to match the Arduino Leonardo silkscreen. If you need the references, use the [Hide References plugin](https://github.com/joelsa/kicad-hide-references-plugin) which can be easily installed via the Plugin and Content Manager.

# BOM

The [BOM](https://raw.githubusercontent.com/eltorio/leonardo/main/Leonardo_Rev3e.html) was automatically generated with [python/bom.py](https://github.com/eltorio/leonardo/blob/main/python/bom.py) add this script in the BOM dialog.  

The html BOM was converted to MarkDown with https://www.convertsimple.com/convert-html-to-markdown/
