Warm white and animating RGB 3W LED PCB

These nice little displays measure 31mm diameter and have 12 surface mount warm white LEDs mounted around a 5050 RGB LED in the centre. When you first turn them on you get warm white light, but turn off the power and back on again quickly and you can access the RGB LED. Cycle resets after power is off for about 5 seconds.

The board has the microcontroller etc on the rear, and there are 5V + and - contacts on both sides of the PCB.

All modes (each mode is an off/on cycle of power) are:
• Warm white
• RGB slow fade between colours
• RGB quick change (2 seconds or so) between colours
• Red
• Green
• Blue
• Cyan (green and blue)
• Purple (red and blue)
• Yellow (red and green)
• White (red, green and blue)
