Assembly Instructions
This kit can be assembled in two ways; using mostly surface mount or through-hole parts. This set of
instructions covers the through-hole component options where available; for those interested in a
challenge you can use the surface mount parts in place of the through-hole parts to complete the project.
Step 1: Unpack contents of package and
compare with the Bill of Materials above to
ensure all parts are accounted for. If any
parts are missing, contact Parallax directly
(contact information is at the top of the first
page).
Step 2: Wash the PCB with alcohol to clean
the surface of any grease or oils, and allow it
to dry before soldering.
Step 3: Solder is in place on the board for U1
and U2.
Place the P8X32A-Q44 on its pad (U1) so the
Pin 1 indicator on the chip and on the board
are matched, and the legs of the chip are
aligned with solder grooves.
Then, add some flux.
(To position the chip you can use tape or a
non-conductive tool like the one shown;
which worked very well.)
