39 on the arduino, there's a hole on the top left.

51 it is related to wire gauge.
52 bigger numbers mean larger screw.
53 smaller numbers means smaller screws.])

89 as it was before tightening the screw.]))

93 can the arduino board still rotate a few degrees?
94 warning, if you rotate the arduino board too much, you
95 will unscrew it from the deck and you'll have to screw it
97 rotating a few degrees should be ok.]))
