This 8 digit seven segment display module (HCMODU0082) 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. To panel mounting the module has 4 mounting holes and 4 brass pillars with screws are supplied.

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 we have written an exclusive library (HCMAX7219) than allows you to effortlessly display and scroll alphanumeric characters across one or more modules. This can be downloaded from the software section of our support forum (see link below).

Cable is not supplied. If you require a cable, please see our range of dupont cables here.
