IDUINO for maker’s life User Manual For 8 x 8 LED RGB Matrix Display Driver Board (ST1149) www.openplatform.
IDUINO for maker’s life Description: This is a magic RGB LED dot-matrix driver compatible with Arduino .It pairs the M54564 with a single DM163 constant current driver. By using the DM163, it gains three 8+6bit 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.It is easy to cascade by IIC and Power interface.
