§
After placing the parts, please double check for correct polarity.
Check the PCB tracks for solder bridges and short circuits created
by accident. This would cause faulty operation or, in the worst
case, damage. You can remove excess solder by putting a clean
soldering tip on the spot. The solder will become liquid again and
flow from the soldering spot to the soldering tip.
Assembling the kit
You can skip this part if you have purchased a ready-built module.
Preparation
Put the sorted components in front of you on your workbench. The
separate electronic components have the following special features you
should take into account to prevent mistakes in assembling:
Resistors
Resistors reduce current. Their mounting orientation is of no
importance. The value of resistors for smaller power ratings
(under 5 W) is indicated through colour rings. Every colour
stands for another figure. The colour ring in brackets indicates
the tolerance of the resistor which here is of no importance.
