I recently purchased a set of Female Header - SMD-4P-2.0mm-20Pcs connectors.
My problem is that they do not fit with any of my solderless breadboards or any prototyping boards that I have. All my boards are standard and measure out to be 2.0 mm pitch. The pins on the connector do not line up with the holes in the breadboards or prototyping boards.
Why do these connectors not fit? What am I missing?
