Package: 1 MAX7219 Dot Matrix Module Microcontroller Red 2.20CM Dupont Line 5P MAX7219 is an integrated serial input/output common-cathode display driver. It connects a microprocessor and an 8-digit 7-segment digital LED display. It can also be connected to a bar graph display or 64 independent LEDs. It includes an on-chip B-type BCD encoder, multiple scan loops, segment word drivers, and an 8*8 static RAM to store each data. There is only one external register used to set the segment current of each LED. A convenient four-wire serial interface can be connected to all general-purpose microprocessors. Each data can be addressed without rewriting all the displays when updating. MAX7219 also allows users to select encoding or not encoding for each data. The entire device includes a 150μA low-power shutdown mode, analog, and digital brightness control, a scan limit register allowing users to display 1-8 bits of data, and a detection mode that allows all LEDs to emit light. Only 3 IO ports can drive 1 dot matrix! No flicker during dot matrix display! Support cascading! Module parameters: 1. A single module can drive an 8*8 common cathode matrix 2. Module working voltage: 5V 3. Module size: length 12.8 cm X width 3.2 cm X height 1.3 cm 4. With 64 fixing screw holes, the hole diameter is 3mm 5. Module with input and output interface, support multiple module cascade Wiring instructions: 1. The left side of the module is the input port, and the right side is the output port. 2. When controlling a single module, you only need to connect the input port to the CPU 3.
