MAX7219 Dot Matrix Module Display Module

MAX7219 Dot Matrix Module Display Module

MAX7219 Dot Matrix Module Display Module DIY Kit SCM Control Module for Arduino

 

ราคา  320 บาท

 

 

Module parameters:

A single module can drive an 8 * 8 common cathode lattice

2 module operating voltage: 5V

Module size: 5 cm in length X width 3.2 cm x 1.5 cm

4 with four screws hole, aperture 3mm, Our M3 Tongzhu fixed

5 modules with input and output interface, supports multiple modules cascade

Wiring instructions:

Module on the left as an input port, output port on the right.

Control of a single module, simply input port to the CPU

3 more modules cascade input termination module of a CPU, 2 output termination module input and output of the two modules is terminated with the input end of the first three modules, and so on. ..

51 MCU, for example:

VCC → 5V

GND → GND

DIN → P22

CS → P21

CLK → P20

Note :

1.VCC and GND is not reversed, it would burn the chip!

2 the P0 port control 51 microcontroller must be connected to the pull-up resistor, it is recommended that the resistance of 4.7K--10K

Please lattice first inserted into the round hole seat, then inserted into the round hole Block PCB board welding. Lattice word side facing the surface order from left to right pin 123456. PCB board 1 foot square pad!

4 as cathode of the electrolytic capacitors long-legged, short legs for the negative; ceramic capacitors without the positive and negative points.
