MAX7219 digital display control module

This module is compatible with 5V and 3.3V microcontrollers.

You you can use it for Arduino

MAX7219 is an integrated serial input / output common-cathode display driver,

which connects your microprocessor to a 7-segment digital LED display with 8 digits.

Only three IO ports are used to drive the eight digit display.

MAX7219 supports flicker free displays as well as cascading displays.

Wiring instructions(for example, it can connect any IO port,

modified the Port Definition in the program):

VCC: 5V

GND: GND

DIN: P00

CS: P01

CLK: P02

Note:

VCC and GND should not be connected reversed, so as not to burn the chip

Specifications:

Material: PCB + Electronic Components

Power: 5V

Size: 82*15*12mm(L*W*H)

Shell Color: Blue & black

Green Board:

MAX7219 is an integrated serial input / output common-cathode display drivers, 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 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 need three IO ports can drive eight digital tube!

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

100% brand new, high quality

Power supply: 5V

Material: PCB + electronic components

Size: 76*21*11mm/2.99*0.8*0.43"

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

VCC→5V

GND ground →

DIN→P1.0

CS→P1.1

CLK→P1.2

Notice:

Do not reverse VCC and GND, so as not to burn the chip

The P0 port of the 51 microcontroller needs a pull-up resistor. If your device does not have a pull-up resistor, you can connect to the data lines of other ports.
