2. Construction description of the SMD equipped board:
For the construction of the SMD of equipped board is not necessary much.
A soldering iron, with fine soldering tip, tin-solder and an ohm metre.
Step 1: the power supply
Check:
To test, the 3,3V a pin row can be
soldered at position J11. Now
3.3 V should be measurable here!
Follow the next section only
with successful tension
measurement!!
Manual to build the SMD pre fitted Hardware
As the first we equip on the top of the board the 3-pole
connection clip X2.
With supply of the LightControl about an external source
(recommended) both solder jumpers SJ6 and SJ7 stay open. If the LC
about the tension DCC the both solder jumpers must be closed and X2
not equipped..
The LightControl can be supplied with DC voltage and AC voltage with
the help of the rectifier the suitable polarity always lies with the switch
regulator. Even if you supply the module with a DC voltage the rectifier
equipped remain, therefore receive a polarity protection.
important: Pay attention with this variation to the right polarity in the
clip X2 (X2-2 und X2-3).
The power supply for the light control is ready.
This picture has an insertion divergence, however, shows the measuring result!
