Step 2:
Follow up by 2.1mm power jack.
Solder it by placing board to the
support as shown
Solder the two types of switches
to there respective places.
Three pin switch is on-off switch
and sw2 i.e. bigger switch is an
output voltage adjustable switch.
Step 3:
In this step you will solder the capacitors and the LEDs.
The Red LED is put into LED1 and Green LED is put into LED2. The red
indicates whether the board has input power. If red LED glows that means
your board is connected to the input. To get output, you need to switch
on the switch first. Then green LED glows according to the voltage you
choose.
• Check polarity of the capacitor.
• Long one represents positive.
• Solder all the capacitors to there
respective positions.
• Check the polarity of the LED and
solder according to it
• Bigger terminal indicates positive
and smaller is negative.
