8x8 Serial Dot Matrix Module

This serial LED dot-matrix module consists of an 8x8 grid of red LEDs. It is based on the Maxim MAX7219 serial LED controller IC which gives the module the ability to not only be programmed via the serial (SPI) interface of a microcontroller, but also allows it to be daisy-chained so that multiple modules can be linked together and controlled with just 3 digital pins (Din, Clk, CS). The driver board for the module does not extend beyond the LED module itself and so multiple modules can be added as both columns and rows without any gaps between each module allowing for much larger displays to be constructed. 

For Arduino uses we have also written an exclusive library (HCDisplay) which will help you develop your project with the minimum of effort. This library can be downloaded from the support section of our support forum here:
