jivith MAX7219 Dot Matrix Module For Arduino Microcontroller 4 In 1 Display with 5pin Line Electronic Components Electronic Hobby Kit

The MAX7219 8×8 Dot Matrix Red Display Module has four 1.3? 64 LED dot matrix displays with built-in MAX7219 serial LED drivers. MAX7219 LED DRIVER : The MAX7219 is a popular and flexible 7-segment, bar graph and dot matrix common cathode LED driver that supports many functions for controlling LED displays. The driver provides flexible individual LED control as well as basic functions such as turning the display ON/OFF and adjusting the LED brightness. The MAX7219 communicates with a uC via a 3-wire SPI bus. Once the display is updated by the uC, the MAX7219 then takes care of all the work of keeping the display refreshed, so it removes that overhead from the uC which can be off doing other more important things. FEATURES : Four 8×8 LED Matrix Displays with 1.3? high red displays. Built-in MAX7219 LED Drivers for each display. SPI 3-wire serial interface for easy hookup to uC. Can daisy-chain multiple modules together for larger displays.
