MAX7219 8x8 Dot Matrix Display Kit

Kit With All Components

The mini 8×8 Dot Matrix LED Display Module is based on the MAX7219 dot matrix module chip. It is a serial input common-cathode driver that interfaces microcontrollers to LED matrices.

All common microcontrollers including Arduino models can be connected to this module.

A connection is made by using the 4-wire serial interface. Each output can be addressed without refreshing the entire display. This module requires only 3 I/O lines for driving the display, making it ideal for your microcontroller projects. Features such as display brightness can be adjusted in software to the MAX7219.

Assembly Details

Each board only requires the installation of two headers for the display (supplied) along with a right-angled Data Header (all included). When installing the display on the board, ensure the Locating Tab is positioned towards the bottom of the board, with the Data In header located on the right side. Installing the display backwards will result in its damage.

For more detailed information on the MAX7219, see the manufactures specification sheet.

Note: Each board comes as a kit.
