STEP 6: Add right-angle headers and speaker
Add the right-angle headers to the board.
Add the 6-pin header in location
J2
, and the 3-pin
header in location
J3
. The pins fit loosely in the holes.
It may be helpful to tack them in place with a piece of
tape (touching the plastic part only) while you solder
the first pin.
Check after soldering the first pin to make sure that
the header pins are level to the board.
Part
#8
is a magnetic speaker/buzzer.
Add this component to location
L1
in the
upper left corner of the circuit board.
The speaker has a marking on the top (“+”) to indicate
its orientation. (There are also corresponding marks
on the bottom side for + and -.)
Insert the speaker into the board with the “+” pin into
the matching “+” labeled hole on the circuit board and
solder it in place.
Part
#9
is an LED driver chip.
(Type STP16DP05B1R or similar)
There are two of these, that go in locations
U2
,
U3
.
First, figure out which way is which on the chips.
The most important feature to notice on the
chips is the “half-moon” indentation at one
end of the chip. This is the polarity marker.
(Other markings on the chips may vary.)
