Schematic
I've played around with Nokia LCD modules from ebay for some time and even exchanged the 0805 leds on them to some other colour. But I want to be able to change the colours of the backlight in real time so I designed this board.
I've copied for the most part the schematic from the ebay module except I added 3 extra pins on the pin header to for the anodes of the LEDS, one for each color.
The resistor values were later tested and 47 ohms resistors were chosen.
