Product Description

MAX7219 digital display control module. Works great for Arduino.

This module is compatible with 5V and 3.3V microcontrollers (51/AVR/STM32, etc). (ive tested both and they work well!)

MAX7219 is an integrated serial input / output common-cathode display driver, which connects your microprocessor to a 7-segment digital LED display with 8 digits.
Only three IO ports are used to drive the eight digit display. MAX7219 supports flicker free displays as well as cascading displays.
Comes with a Straight 5 pin header and a Right angle 5 pin header.
Power: 5V

USES the LedControl libaray: https://github.com/wayoda/LedControl

Wiring instructions: you can actually pop open the example programs in the LedControl Libary and look at the pin settings or change them.
