The Arduino UNO has a number of connector blocks, e.g. the A0-A5 block. I want to design a PCB using Fritzing that has the same type of connector block. What is the part name for this type of connector, and is there a part with the ability to have a variable number of connectors, like what can be done with the Fritzing generic IC part?
What you want is the generic header part. In the “CORE” bin, first item under the “Connection” group. The icon shows a single female pin, but once placed, inspector can used to set several parameters. The one of interest here is the number of pins. The defaults are probably good for the rest, though you might want to have a look at the hole size options
