MAX7219 Dot Matrix Module Display Module with Dupont Line Kit for Arduino
.MAX7219 is an integrated serial input/output common cathode display driver that connects a microprocessor with an 8-bit digital 7-segment digital LED display. It can also be connected to a bar graph display or 64 individual LEDs. It includes an on-chip B-type BCD encoder, a multi-scan circuit, a segment word driver, and an 8*8 static RAM to store each data
.Only one external register is used to set the segment current of each LED. A convenient four-wire serial interface can connect all common microprocessors. Each data can be addressed without updating all the displays when updating
.MAX7219 also allows the user to choose to encode or not encode each data. The entire device contains a 150μA low-power shutdown mode, analog and digital brightness control, a scan limit register that allows the user to display 1-8 bits of data, and a detection mode that allows all LEDs to glow
.Only need 3 IO ports to drive a dot matrix! There is no flicker in the dot matrix display! Support cascade! Module parameters: A single module can drive an 8*8 commuter lattice
.With 4 fixing screw holes, aperture 3mm, can be fixed with our M3 copper posts
.Module with input and output interfaces, supporting multiple module cascading
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. When multiple modules are cascaded, the input of the first module is connected to the CPU, and the output is connected to the input of the second module. The second module The output is connected to the input of the 3rd module, and so on... Take 51 MCU as an example: VCC → 5V，GND → GND，DIN → P22，CS → P21，CLK → P20
