DropLit Assembly Guide
The four plastic bearing rollers specified are being
used as spacers to stand the Arduino Uno off the base
plate a small amount. Go ahead and set them down over
the mounting holes as shown on the right.
Slide the base plate off the edge of your work
table so the portion the Arduino Uno mounts to overhangs
a small amount. Insert the four #2-56, 5/8” pan head
screws into the mounting holes.
Thread a #2-56 finish nut on to each
screw and gently tighten with a P1 Philips
screwdriver. Take care to not crank it down
too hard – you'll crack the Arduino Uno's
circuit board!
