The problem has now been improved! Please rest assured purchase We need your voice, so our customers keep improving our shortcomings! The test program: MAX7219 Dot Matrix Module For Arduino Microcontroller 4 In One Display with 5P Introduction: MAX7219 is an integrated serial input / output common-cathode display driver, it connects the microprocessor 7-segment digital LED display with 8 digits, you can also connect a bar graph display or 64 independent LED. Thereon including a B-type BCD encoder chip, multi-channel scanning loop segment word driver, but also a static RAM 8 * 8 for storing each data. Only one external register is used to set the segment current of each LED. A convenient four-wire serial interface can be connected to all general-purpose microprocessor. Each data can be addressed in the update do not need to rewrite all of the display. MAX7219 also allows each user to select a data coding or non-coding. The entire device contains a 150A low-power shutdown mode, analog and digital brightness control, a scan-limit register allows the user to display data bits 1-8, and one for all LED luminescence detection mode. It requires only three IO ports to drive a dot matrix! No flicker when the dot matrix display! Support cascading! Parameters: 1. A single module can drive a total of 8 * 8 dot matrix overcast 2. Working voltage: 5V 3. Size: *12.8 cm*3.2 cm *1.3 cm (L*W*H) 4. With 64 fixing screw holes,
