Overview
MAX7219 RED LED 8 DIGIT DISPLAY MODULE


MAX7219 is an integrated serial input / output common-cathode display driver, which connects the microprocessor and 8 digit 7-segment digital LED display, you can also connect a bar graph display or 64 separate LED. Includes an on-chip type B BCD encoders, multi-channel scanning loop, segment word driver, but also a 8x8 static RAM that stores each byte of data. Only one external register is used to set the current of each LED segment.

A convenient four-wire serial interface can connect all common microprocessor. Each data can be addressed in the update without rewriting all displays. MAX7219 also allows the user to select each data encoding or no coding.
The entire device includes a 150μA low-power shutdown mode, analog and digital brightness control, a scan-limit register allows the user to display 1-8 bit data, there is an all LED light detection mode.

Only requires three IO ports to drive eight digits.


0.36 inch and four digital tube one common cathode LED

The module compatible of 5v/3.3v microcontroller(51/AVR/STM32...)


Wiring instructions (a program, for example, you can pick any IO port definition can be modified in the program):


VCC→5V
GND→GND
DIN →P00
CS   →P01
CLK→P02

Note:
1.do not reverse VCC and GND it will damage the chip.
2.51 MCU P0 port requires pull-up resistor, if your device does not have a pull-up resistor it can be connected to another port pin.

Package included:

1x MAX7219 Module
4x 
Copper Pillar
4x Screws
