Hello, I am looking for a fritzing part for this type of fpc connecotor (0.5mm pitch 12 pin) ((But if available to change #pin number of and pitch in inspector is even better), if there is a part already i can’t find it sorry.
Not enough information here to do anything with. If you want just the connector, there is an odd pitch 12 pin fpc connector in this post (and it looks like the breakout board may be available in the Adafruit repository)
If that isn’t what you want (and it probably isn’t as it is 0.7mm pitch not 0.5mm) then you need to specify if you want the breakout board to 0.1in pins (which is easiest) or the SMD connector which would require a data sheet with pcb layout footprint to make. Digikey or mouser likely have connector data sheets (a 12 pin 0.5mm pitch connector should be fairly standard.)
Then you need to find the data sheet with a pcb footprint for a connector that will do what you want. There don’t appear to be any parts for 12 pin fpc connectors (there are 20 and 40 parts around.)
This part should do what you want. To get DRC to pass because of the fine pitch I had to set the limit down to 0.005in. Before ordering boards print the pcb footprint out at 1:1 scale (the default) and check it against a real part. The footprint is as the data sheet but they don’t show the connector outline in relation to the footprint so it may be off a bit in silkscreen.
