RGB module is a high-brightness LED module containing red, green, and blue chips. It uses a simple clocked serial interface to receive a 10-bit brightness value for each color, resulting in over a billion possible colors.
Each RGB modules have four input wires, they are DC negative for R, G,B seperately and a shared positive connection. Controlled by a micro computer based RGB LED controller, every color current receive different signal from controller and the three colors mix together result in millions color.
Each input is buffered and output on the other side of the module. This allows each ShiftBrite to repeat the signal to the next, allowing longer cable runs between elements without excessive loading of microcontroller I/O pins. You can parallel connect any RGB module together.
For different application environment, we have different type of micro controller for you, here is a brief description for you(RGB led module)
