40x RGB LED Controller with 8-bit PWM and Selectable Patterns

 
A relativity simple driver I have designed for use in Infinity Mirrors, Case Mods and anything that could use some color.

Controls 40x Common Cathode RGB LEDs in 8 channels with 8-bit PWM, 16 million color combinations.

Five groups with 8 independently controlled RGB LEDs each, are arranged end to end (square or a loop) and together with seamless patterns it appears that all 40 of the LEDs are controlled by themselves.

Driver measures 2.5" x 3.5" x >1"

Kits including PCB+ all component parts and 40x 5mm RGB LED can be purchased in my store at www.ChromationSystems.com

or a Developer Package with all the files needed to recreate this project can be Found Here

Add a suitable PSU and matching panel mount barrel jack to your Order

The PCB for this project is easy for a moderately skilled solderer, wiring the light bars is confusing, be sure you know what needs to be done and can understand directions before attempting this project.

It is set up for 5 volts Input at 1.2 Amp ( Safe Estimate ). But there is a spot for a 7805 if the input current must be more than 6 volts. Not recommended as most 7805s can't handle enough current for all 40 RGB LEDs.

Complete Info is Found in The Datasheet
