MAX7219 CWG 8-Digit LED Display Digital Tube Control Module Works with Official Arduino
Main Features: ● MAX7219 is a kind of integrated serial input / output common cathode display driver, it connects microprocessor and 8 digit 7 period of digital LED display, also can be connected to the bar graph display or 64 independent LED. ● It includes a piece of type B BCD coder, multiple scanning circuit, period of word drive, but also an 8 x 8 static RAM used to store every data. ● Only an external register used to set each LED segment current. ● A convenient four wire serial interface can connection all general microprocessor. ● Each data can be addressed in the update don't need rewriting all the display. ● MAX7219 also allows the user to each data selection coding or not to code. ● Only need three IO mouth can drive eight digital tube. ● Digital tube display when flicker free and it supports cascade.
Note: ● The VCC and GND don't pick back so as not to burn out chip. ● 51 SCM P0 port need connected to pull resistance, if your SCM not connected to pull resistance, can will data line received other port.
Type: 8-Digit LED Display Digital Tube Control Module Mainly Compatible with: Ardunio
