This Arduino compatible board is specifically designed to drive a 3 colour RGB LED dot matrix displays and uses an ATmega328p device loaded with the Arduino bootloader. This allows the development board to be programmed directly from the Arduino development environment (via a suitable TTL serial adaptor). A constant current LED driver provides a PWM hardware interface to to an attached LED module. Designed to be used in conjunction with our RGB LED matrix module (HCMODU0053), this will allow display of any full colour (24bit) 8x8 pattern. To aid in writing your own sketches we have also created our own library which will allow you control the display including scrolling of text and numbers with the minimum of effort.

Besides priding header sockets for the RGB LED module, there are additional interfaces for serial and I2C which allow for programming the board via the freely available Arduino development environment and are arranged in a way so that multiple development boards can be 'daisy-chained' to make up larger displays.

Full 24bit RGB colour control with 6 bit colour correction

Serial and I2C interfaces allowing for daisy-chaining of additional modules
