I’m looking Fritzing part library for N2524-6003-RB (IDC header 2x12) unfortunately, no sight of light to locate this library. I’ve very much appreciated it if you could share the library. I have attached the drawing screenshot.
You can then use Inspector (the lower right window) to set number of pins, sex, and single or dual row. Dual row renders poorly in breadboard however (it is on my list of things to fix)
here I changed row from single to double, and number of pins to 24 (2*12) and it creates the correct pcb footprint you want but a single line connector in breadboard.
