Step 7: Following the schematic, you can
identify each part placement on the board; for
example, C4 is a 1 µF capacitor and R3 is a 10
kΩ resistor. You may notice that there are 2
components for many of the connections; this
R3 pad for 10 kΩ
is because there are two styles of components
through-hole resistor
for this kit.
Do not connect both the surface mount
and through-hole components for a
given location, as that will alter the
operation of the whole unit.
R3 pad for 10 kΩ
A good rule when soldering is start from the
surface mount resistor
inside and work out, so I am starting wit the 5
MHz crystal and work clock-wise, leaving the
header pieces for last.
Step 8: The next components to put on will
be the capacitors and regulators.
C1 - 10 µF capacitor
C4 - 1 µF capacitor
U3 - 5 V regulator
U4 - 3.3 V regulator
The regulator with “117-5” etched on it is the
5 volt regulator and should be soldered on
U3.
Step 9: Continue soldering on the following
components.
C3 - 10 µF capacitor
C2 - 10 µF capacitor
R1 - 470 Ω resistor
D1 - Red LED
J3 - 2-pin jumper
J1 - power jack
