This Arduino based (ATmega328P) RGB LED matrix driver platform based gains three 8+6-bit channels of hardware PWM control thanks to its LED driver. Its design allows you to easily change or write firmware using the Arduino IDE.
Features:

1. 8 bits colours support with 6 bits correction for each colour in every dots
2. hardware 16 MHz PWM support
3. without any external circuits, play and shine
4. dedicated GPIO and ADC interface
5. hardware UART and IIC communication with easy cascading
6. 24 constant current channels of 100 mA each
7. 8 super source driver channels of 500 mA each
8. driver board is based on ATMEGA328 and works with IDE
