How can I add soldering holes, which are attached to IC pins, in Kicad?

Question

I'm now almost done with a schematic in Kicad's Eeschema, but some links to the "outside world" are still missing, and I don't know yet how to add them to the schematic, so that they will appear as soldering holes in the PCB later. Here is the relevant part of my schematic:

As you can see, it's all about 7 pins on a microchip (TDA7318 mixer): 3 of them belong to its I²C interface, and the other 4 ones are audio outputs, which shall lead to an amp residing on another PCB.

Now I'd like to know the following: Which parts shall I add to the schematic, so that Pcbnew will add one soldering hole per pin? For the I²C link, I've already added a GS3 connector (sadly without knowing whether this is the correct part). In real life, I would attach a level shifter with a 3-pin 0.1" header here. For the 4 audio output pins, I would simply solder one short wire each, which would then lead to the amp PCB.

Any suggestions?

Answer 1

Use Connector_Generic, Conn_01x03 and then for the footprint, choose Connector_PinHeader_2.54mm, Connector_PinHeader_2.54mm:PinHeader_1x03_P2.54mm_Vertical.

If you do any amount of PCB layout, you WILL have to make your own schematic symbols and PCB footprints - either by editing existing parts, or from scratch.

Standard 0.1" pitch connectors are convenient, but the pin holes may be a bit small for wires.

For solder points for individual wires, I use a one-pin schematic symbol (perhaps called "testpoint" in KiCAD's libraries),and a one-pin footprint - you can make the pad in that footprint whatever size is required to accept the wire you are using. I had footprints called "spad35", "spad50", etc. for solder pads with 0.035 or 0.050 inch holes.
