Idea: More LEDs - More Colors

A project log for 384:LED

Mini (1.44'' x 0.94'' or 24mm x 37mm) 8X16 RGB LED Array. 128 RGB LEDs with three LED chip each gives 384.

Some time ago while talking with someone else about this project, the idea came to use RGB LEDs. And there are small suitable RGB LEDs available: 0404 RGB LEDs. So this is what I came up with: 21*8 RGB LEDs ( =168 RGB LEDs or 504 single LED chips):

Problem here is how to control so many LEDs? I am not sure yet but I am planing to multiplex the lines. And driving the columns via some (21*3=63 Bit!) shift registers. I am also thinking of using a Microcontroller which is faster than a ATmega to get a acceptable refresh rate on the Matrix.

The PCBs measurements did not changed much. The goal is still to fit this and a control PCB of the same size into 5x5cm:

Because this project is still in early stage it is possible that I will return to a single color version ( or never built one ).
