just figured out how to grab footprint and symbol data for most (if not all) parts from JLCPCB's catalogue, so this is about to get rather interesting...
@ckie nope, I'm using Altium, and this is part of my ongoing project for making interop with Altium a hell of a lot easier. but the exporter code should be pretty easy to port for KiCAD/whatever use too, once I publish it.
if you're just doing a one-off, I'd recommend installing EasyEDA (it's free) and finding the footprint, and checking/copying the dimensions in the program
@gsuberland do you use kicad? i was suffering with chinese datasheets a few days ago trying to figure out which footprint i want and that could've maybe helped
