NodeMcu V3 parts library

Hi Peter, thanks a lot for your elaborate response which is highly appreciated. The issue is related solely related to the "spacing between the sets of pins". Indeed, the github holds a spacing of 22.86mm (= .9 x 25.4). The LoLin NodeMcy V3 holds a spacing between the sets of pins of 27,94mm. The number of pins per pin row are exactly the same, also the spacing between the individual pins in the row, i.e. .1 in (2.54mm).
Thanks for directing me to the "new part creation" write-up which undoubtedly will give me a lead to start. However, I have taken good note of yr comment that "Parts modification is fairly complex" and thus wish to take you on your offer to make the modifications in this particular case.Board dimensions are 31 x 58mm. Hop I don't bother you too much with this.
