Soldering Skills and Requirements
Pay special attention to part polarity at soldering. Refer to photos to the right.
For BOB boards and LCD soldering refer to photos at bottom for details.
1.
2.
Install parts by the order of part list. Start from the back side of main board.
3.
Perform power-up tests as suggested in the part list.
4.
Complete the steps in "Get Ready" and understand soldering requirements.
5.
Important! Unused leads under LCD must be cut flush to avoid short to LCD module!

are not required.
TIP:
Do not install J4 if battery is to be mounted on back cover.Insert
the pins into programmer header to perform U4 and U5 programming.
Keep JP2 open if BOB3
is installed. Otherwise
close it.
Identify the holes with labels
on LCD. They should go
with the long strip.
Put LCD onto strips as shown.
Solder pins at corners first. Do
the rest after flatness ensured.
Turn LCD and main board over.
Complete soldering following
same procedures as in C.
Use the small acrylic
tool provided.
Apply solder to one
pin.
Apply solder to the
corresponding pin on
main PCB.
Put BOB to place
and align pads.
Maintain BOB upright
and fix it by melting
the solder.
Finish the rest pins.
