NOTES:
This instruction contents high definition pictures. If anywhere is uncertainty, PCB view
can magnify and an interested component may to view in details
The side of the board that has printed component marking is the "component side". This
means that components must mount by inserting them down from the printed side.
Make sure that the components mount on the proper side of the PCB!
Prior to beginning an assembly, make sure to have a well-lighted, well-ventilated
workplace. Make sure that all of the electronic assembly tools are available.
1. Low Voltage Power source components preparation for insertion into the board
U1
LM7805
C7
220uF, 25V, Electrolytic
C2
0.1uF, Ceramic
D1
1N4004
FUSE
FUSE 0.5A
Power socket
5.5mm x 2.1mm PCB DC Jack
2.1. Bend U1 integrated circuit leads.
2.2. Bend the two leads of the C7 capacitor so that they form a right
angle to the capacitor body
2.3. Bend the two leads of the fuse and diode D1 so that they form a right angle to the component
body.
2.4. To install, place the leads of the component through the appropriate holes and press the
component down against the component side of the PCB.
