Symbols and footprint support for Arduino in KiCad 7.x

colporteur

I've encountered some Design Rules Checker warning messages when creating a PCB, that appear to be related to the libraries provided at https://github.com/Alarm-Siren/arduino-kicad-library . I'm wondering if members have any experience using the libraries provided at this link.

The libraries appear to be the official support for the Arduino. I used the Arduino_Mega2560_R3_shield footprint on a test PCB without adding any components and received the same warnings.

This is the first time I have used these libraries. I followed the install instructions at the site and also tried installing the libraries manually. I get the warning no matter how they are installed. I noticed some anomalies when I looked closer at the templates. The lines highlight some of them. (i.e. there are a few orphaned D0's). These appear to be what DRC is complaining about.

Since I haven't used these libraries before I curious if anyone can share their experience.

  • Hi Sean,

    They are just warnings so they are unlikely to cause harm, having said that, as you say, it looks like it is related to that text etc.

    The library is just created by an individual, not an Arduino employee, so it may work or it may not. I don't trust random libraries because they are frequently faulty, and I would rather be making mistakes of my own creation.

    Since (from what I can tell) Arduino have not published an official library for KiCad, and since I'm very familiar with EAGLE (which is what they have published) I was able to convert it into KiCad format directly from the official Arduino EAGLE files, and placed the Arduino Mega2560 Rev 3 symbol and footprint on GitHub.

    If you want to see how it is done, it is documented here:  Working with KiCad 7: Importing EAGLE files  

    There may be errors since it is not an automated process, but personally I would trust this more. If you decide to use it, you may wish to edit or refine it, but it is usable as-is. Please double-check your PCB files before you submit them, if this library is used, since I have just created it and clearly it's not been tested.

    If anyone else can spot any errors, I'd be grateful for the information. I probably won't incorporate any enhancements (like holes or silkscreen) unless someone submits a merge request, but I will correct any physical/electrical errors.

    This library has zero DRC errors with KiCad 7.

    Forgive my ignorance does this include the symbol also.

    I was using a Mega 2560 symbol that got replaced. The replacement symbol switched around the voltage and gnd groups. Pain in the ***.

    I've redone all schematic and PCB work with the new file from this source. Then I discovered the error. SHITE!
