    Description
    :
    MAX7219 is a kind of integrated serial input/output common cathode display drive, it connects the microprocessor with eight digit seven segment digital LED display, also can connect the line graph display or 64 independent leds. It includes a piece of type B BCD coder, multiplexing scanning circuit, drive period of word, but also a 8 * 8 static RAM is used to store each data. Only an external registers used to set the period of current of each LED. A convenient four wire serial interface can join all general microprocessor. Each data can be addressed in the update does not need to rewrite all the display. MAX7219 also allows users to each data selection code or code. The device contains A 150 mu A low-power shutdown mode, analog and digital brightness control, A scan limit register allows the user to display 1-8 bits of data, there is also A let all LED detection mode. You just need to three IO mouth drive 1 lattice! Dot matrix display flicker-free! Support cascading!
    Module parameters:
    1. A single module can drive an 8 * 8, a total of Yin lattice
    2. The module working voltage: 5 v
    3. The module size: 12.8 cm X 12.8 cm X 1.3 cm wide
    4. 64 fixed screw holes, aperture 3 mm
    PACKAGE INCLUDED:
    1Pcs MAX7219 lattice module 4 in 1 LED dot matrix module 8x32 dots
    1Pcs 20 cm dupont line 5P
    Clock example on the front pic is just example what you can build with this display and other components not included.
