PCB SCHEMATIC
DESCRIPTION OF THE SCHEMATIC
Diodes LED
Resistors R1 and R2 are the current limiters for D1 and D2. Choose the value according to the brightness of the led. Recommended values are 2.2k – 4.7k for regular LEDs.
Power supply
Capacitors C1 and C2, in combination with R3, filter the noise from the power supply.
Diodes D1 and D2 are placed for reverse polarity protection. If the effect PCB already has inverse polarity protection, don’t place D2, and substitute D1 by a jumper.
