 This product is shipped from Sydney, Australia. Worldwide shipping available- we ship to USA, Canada, New Zealand, UK, EU and Non-EU countries.

This 8 digit seven segment display module is based upon the Maxim MAX7219 LED display driver. The module uses two standard 4 digit seven segment displays to display a total of 8 digits in RED with decimal point. A convenient input and output header allows additional modules to be daisy-chained and controlled with just just 3 digital IO pins. 
The Maxim MAX7219 driver allows for each segment of up to 8 digits (with decimal point) to be controlled individually from a serial interface. An 8x8 static ram area stores each digit and multiplexing the display is handled automatically. 
If you plan to use this module with an Arduino board there is a library (HCMAX7219) that allows you to effortlessly display and scroll alphanumeric characters across one or more modules. This can be downloaded http://blog.hobbycomponents.com/?p=334.
