With an ESP32 Devkit I have the problem that the board is too wide for the standard breadboard - I had to build an individual one from two breadboards and would like to create this as a component in Fritzing.
I understand that you can only modify existing components in the new component editor, but editing is not possible at all with breadboards, and unfortunately there are no clear instructions for an alternative on the Internet.
My question - can someone tell me how to design my own breadboard and import it into Fritzing? Thank you very much.
Making breadboard parts is complicated. Your best bet would be to duplicate two breadboards and move them next to each other in the sketch. There are also cut apart breadboards that I made for someone that wanted to do the same thing here:
