MAX7219 8 x 8 Dot Matrix Display(Red) Module

This is a MAX7219 8x8 Dot Matrix Display Module.The Max7219 Led Dot 8x8 Matrix is an integrated serial input/output common-cathode display driver connected to a microprocessor and has an 8-digit 7-segment digital led display that can also be connected to a bar graph display or 64 separate LEDs. Each data is stored in an 8 x 8 static ram on the BCD Encoder, which includes an on-chip, multi-channel scanning loop word drive. To set the current of each led segment, only one external register is used. All general-purpose microprocessors can be connected using a simple four-wire serial interface. Each data can be addressed in the update, which eliminates the need to rewrite the entire display.
