  1. library for MAX7219 and MAX7221 Led display drivers (ZIP)

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
