Step 1
Assembly the Main Board
1.
Complete the steps in "Get Ready" and understand soldering requirements.
2.
Install parts by the order of part list. Start from the back side of main board.
3.
Pay special attention to part polarity at soldering. Refer to photos to the right.
4.
For BOB boards and LCD soldering refer to photos at bottom for details.
5.
Perform power-up tests as suggested in the part list.
NOTE
: This photo is for PCB version H. PCB
version I is slightly different. Some parts have
been omitted or changed to SMD. Please see the
part list. Performance is not affected.

Soldering Skills and Requirements
1 Put leads through mounting from installation side of
PCB. Ensue they evenly touch PCB (picture below).
2 Solder at the other side of PCB. Solder should fully
fill and cover soldering pads.
Avoid bridges with
neighbering pads.
Cut unused leads
