Colorduino V1.3

From ITEAD Wiki
Jump to: navigation, search



Colorsduino is a magic RGB LED dot-matrix driver compatible with Arduino . Colorsduino pairs the M54564 with a single DM163 constant current driver. By using the DM163, Colorduino gains three 8+6-bit channels of hardware PWM control of the LED’s freeing up the MCU from having to implement it in software. This gives the ATmega328 more CPU bandwidth for performing other tasks. Colorduino is easy to cascade by IIC and Power interface.
