[Meggy Jr RGB]
[14]
STEP 12: Add the Socketed LED Matrix Display and the Button Switches
Add the socketed display in location
U4
.
Set the socketed display into its
position (U4), with the labeled edge
on the left side as shown.
Position the display flat, resting
gently (near the top) on large
capacitor (C3). The pins of the
socket should barely extend past
the back side of the circuit board;
solder them in place.

:
After the socket pins are soldered in place, the LED
display can be removed (with a firm rocking motion)
and put back in place if necessary.
(Almost there!!!)
Part
#19
is a small tactile button switch.
This is an
OPTIONAL PART
that is not required (but might be nice).
If installed, the Meggy Jr RGB will be reset (i.e., rebooted) when you
push this button. If you want it,
snap
it into location
S1
(Reset), and
solder all four pins from the back side.
Part
#20
is a large tactile button switch.
Six of these
snap
into locations
b0
through
b5
: the
gameplay button locations. Each has six pins: four metal
pins and two plastic pins that help keep it in place.
Be careful! When this snaps into the board, those metal
pins can poke you, so don’t put your fingers right where it
will snap through. (And solder the four metal pins, but not
the two plastic ones.)
