KiCad 6 has recently launched, and uses a different system for libraries. I need to update

Reset pins are currently set to Input, but they should be Open Collector to reflect the fact that they can be pulled low by the Arduino, both by the reset button and by the serial controller resetting it during programming. Doesn't fully encompass the behaviour (since there's also an internal pullup) but its closer at least.

The screw holes in the Arduino_Micro_Socket footprint are 1.016mm in diameter, but the Arduino Micro itself has 1.2mm holes.
Change hole size to 1.4mm (0.2mm bigger than Arduino's own size, to match with standard KiCad practice and the rest of the library).

Expand the front courtyard a little and add USB area to silkscreen to make it easier to plug it in the right way around.

The schematic for the Arduino Micro has an IOREF pin, but the Arduino Micro footprint does not causing a mismatch. In this case the footprint is correct: the schematic needs to have the IOREF pin removed.

Since there are many Pro Mini Clones on ebay (and I have more then 10 of them) it would be nice to support it here.
All of my board's are about 33x18mm in size

Add parts for the Arduino Nano & Mini as Sockets. Need to investigate these parts, find physical dimensions and pinouts etc.

For consistency, change all 3.3V power pins to use 3V3 as the pin number (or 3V3x if there's more than one 3.3V pin, e.g. 3V31) and 3.3V as the pin name.
This affects all existing boards.

According to standard IEEE 315-1975, these components should use the reference designator XA?, where X means "socket", A means sub-assembly and ? is a placeholder for the part's unique number within the schematic.

The Arduino M0 Pro footprint is not correct.

At the moment it 'borrows' the Leonardo footprint, but the Leonardo only has one Micro-USB port not two like the M0 Pro does.

The closest match would be the Arduino Zero, however that has an ATN pin which the M0 Pro lacks. Therefore it looks like the M0 Pro needs its own footprint which is basically identical to the Zero but with the ATN pin removed.

Note that the M0 is not affected and can continue to borrow the Leonardo footprint.

Though the old links still work, they're now redirects to the "real" page. Since its safe to assume these redirects won't work forever, the links need to be updated to the new style.

Change the power pins on all schematic components to Power Input so that joining them together will not cause ERC errors, as discussed in issue #1 . This will mean that in some cases the user will have to attach a PWR_FLAG to the relevant net, but that's less of an issue than having an unavoidable error for joining together pins in such a way that is not an error.

All symbols were missing their Footprint Mappings. They have footprint filters, but not mappings.

Switch license from LGPL to CC-BY-SA as it is more appropriate for use with artwork.

On review of the library, there is a startling lack of consistency between the different footprints.

This issue encompasses the following work:

• Add courtyards / fab outlines for screw holes
• Use rectangular pads for all GND pins, and only GND pins
• Use silkscreen to mark the location of the D0 pin only. Put the label on both back and front silkscreen.
• Add Fablayer labels for Barrel Jack / USB. Remove any that already exist on the Silkscreen layer.
• any outlines or reserved space for protruding components that are on the Silkscreen layer should be moved to Fab or Courtyard. Also ensure that the outer courtyard conforms to the relevant reserved space.
• Add B.Fab layer outlines for the pin headers on Shield footprints - this will help the user to reserve the space for the pin sockets on their PCB.
• Add F.Fab layer outlines for pin sockets on Socket footprints - this will help the user to reserve the space for the pin sockets on their PCB.
• Add B.Courtyard outlines for shields.
• Shields should have their silkscreen on the Back.Silkscreen layer, not front!

I thought the Arduino 3.3V pin serves as a 3.3V output from the on board regulator. If I make a circuit and try to get a 3.3V out, the DRC keeps popping up an error claiming that I've not connected an output to the input. I don't know if it's Kicad that could have the issue, but that's where I'm at

The Pro_Mini_Clone_Socket symbol has its footprint filter set to Arduino_Pro_Mini_Clone_Socket when it should be Pro_Mini_Clone_Socket.

Thank you very much for creating arduino-kicad-library. It looks like just what I need.

Having created a schematic with your Uno Shield, I am having trouble with the Electrical Rules Checker. There seem to be a couple of problems:

• It doesn't seem to like that I am joining the GND1, GND2 and GND3 nets together
• I am trying to take the 12v power supply connected to VIN and connect it to some 2N7002 MOSFETs, however it doesn't think the 12V power net is driven

I have found Kicad to be really difficult to get started with. If you are able to provide any help, that would be fantastic!

Define a "default" footprint, in addition to footprint filters. This is a new feature in KiCad 6 which I was previously unaware of. It allows enables footprint preview in the symbol selection dialogue.

The "Pro_Mini_Clone_Socket" symbol has its footprint filter set to "Arduino_Pro_Mini_Clone_Socket" instead of the correct "Pro_Mini_Clone_Socket"
