MAX7219 LED Display Control 8 Digit Dot Matrix Module for Arduino Diy Starter Kit MAX 7219 with Dupont Cable

   Smart Electronics MAX7219 LED Display Control 8 Digit Dot Matrix Module for Arduino Diy Starter Kit MAX 7219 with Dupont Cable

   MAX7219 is an integrated serial input / output common-cathode display drivers , which connects the microprocessor 7-segment digital LED display with 8 digits , bar graph can also be connected monitor or 64 separate LED. On type B BCD encoder includes an on-chip , multi-channel scanning loop , segment word drive, but also a 8x8 static RAM for storing each data . Only one external register is used to set the segment current for each LED .

   A convenient four-wire serial interface can connect all common microprocessor. Each data can be addressed in the update does not overwrite all of the display . MAX7219 also allows the user to select each of the data code or not coded .

   The entire device includes a 150μA low-power shutdown mode , analog and digital brightness control , a scan-limit register allows the user to 1-8 bits of data , there is an LED light so that all the detection mode .

   Requires only three IO ports can drive a dot ! No flashing dot matrix display ! Support cascade !

   When cascading multiple modules 3 , output and input termination CPU, the input output termination module of the first two modules of the first one , the first two modules of terminating the input of the first three modules , and so on . ..
