On the motherboard, the tolerances of the holes on the board for the plastic nubs on the bottom of the micro usb socket are a bit off. In my case a tad to wide and the pins don’t reach the board unless I cut off the nubs as they don’t match the holes. Not a big deal of course, just an FYI.
For my own curiosity, are the nubs / pins just standard and that’s why you did holes? Because the 4 outer grounds pins should be good enough to align the socket (those could be a tad longer / through hole to solder them easier IMO).
Anyhow, I’m very much enjoying reading the manual and getting back into soldering, thanks again for the kit!
