8*8 LED 7-color Matrix is discontinued now. We recommend these LCDs, LEDs & Displays as an alternative where you might find other products interested.
A dot matrix display is a display device used to display information on machines, clocks, railway departure indicators and many other devices requiring a simple display device of limited resolution. Even if the 8x8 RGB led dot matrix is commonly used in lots of applications, but it require too much digital pins to drive it. And the software is too complex also.
The 8x8 LED RGB matrix module aimed to solve these problems.Directly drive the 8x8 RGB matrix module via the SPI serial interface. It works with 3-wire digital pins and the hardware SPI interface.The RGB matrix module from DFRobot is Daisy-chainable connection design - vertically and horizontally at the same time.And the high speed data transmission design improves its' display refresh rate.So it's possible to assemble a big RGB Matrix screen.
Unit comes with a Red/Green/Blue full color LED Matrix assembled with a RGB Matrix Backpack Controller.Certainly, it directly supports Arduino. And the library supplied is helpful to drive it much easier.
