| MAX7219 Dot led Matrix Module Led Display Control Microcontroller 4 In 1 Display with 5pin Line For Arduino |
Introduction:
MAX7219 is an integrated serial input / output common-cathode display driver, it connects the microprocessor 7-segment digital LED display with 8 digits, you can also connect a bar graph display or 64 independent LED. Thereon including a B-type BCD encoder chip, multi-channel scanning loop segment word driver, but also a static RAM 8 * 8 for storing each data. Only one external register is used to set the segment current of each LED.
Parameters:
1. A single module can drive a total of 8 * 8 dot matrix overcast
2. Working voltage: 5V
3. Size: *12.8 cm*3.2 cm *1.3 cm (L*W*H)
4. With 64 fixing screw holes, diameter 3mm
5. module with input and output interfaces, support for cascading multiple modules
Wiring instructions:
1. The left side of the module as an input port, an output port on the right.
2. If a single control module, simply input port connected to CPU
3. cascading multiple modules, input and output termination CPU, input the output end of the second module of the first module, the first two modules of the first three input termination module, and so on. ..
51 microcontrollers, for example:
VCC → 5V
GND → GND
DIN → P2.2
CS → P2.1
CLK → P2.0
