Looks like a good start. You probably want more detail on the pwm pins though, I assume one is likely ground and the other the active pwm signal and it would be good for the schematic to show which is which (a quick google search didn’t turn up much technical info on this board, just lots of people selling copies of it with no documentation). You may want to have a look at this tutorial in pars creation as well as Old\_Grey’s videos: > [@A new part creation HowTo (long! So long it is in 2 posts)](http://forum.fritzing.org/t/a-new-part-creation-howto-long-so-long-it-is-in-2-posts/2238): > > (Edit: November 2016: This is an updated (and corrected) version of the original parts creation howto. This version corrects some suggestions (mostly saving Inkscape files as optimized svg which turns out to cause other problems) with the first version and expands the section on parts testing. While there doesn’t appear to be a lot of interest in this subject I’ll make at least this update so the information is as correct as I can get it.) This is a description of how I made the Valor PM6078-00… You can export the part from Frtizing as an fzpz file which will contain the fpz file along with all of the svgs as well which makes it easier for us to make suggestions.
