Title: Is this the matching footprint for the micro USB header?
Post by: newtekuser on April 17, 2023, 12:38:17 am

I've purchased a bunch of these micro USB headers (attached pic) for cheap and would like to use them in my designs, but I'm not sure that this is the right footprint for them.

The seller doesn't answer to my messages so not help from them unfortunately.

Can someone please confirm?

Whenever I am faced with a similar problem, I always look for the manufacturers STEP-file.

When the STEP-file is imported/mapped to the footprint, I instantiate the footprint onto an empty PCB
then invoke the 3D display of the board, including copper pads and plated/unplated holes/slots.

Sort of what I did in my pics but I couldn't find anything on the manufacturer so I added footprints to the pcb and opened them in the 3d view to compare but I still can't tell for certain altough what I've got seems close.

There are over a hundred footprints  for micro USB connectors, and if you buy a bunch of them from some random cheap shop, then there usually is no documentation at all for dimensions and such, and you'll have to reverse-engineer (a.k.a measure) the pin and hole locations and make your own footprint.
