Its a serial input or an integrated output common-cathode display drivers, 7 segment digital led which connects the microprocessor with 8-bit digital display, can also be connected bar graph display or 64 independent LEDs. It includes San on-chip b BCD encoder, a scanning circuit, some words to drive, but also the static ram an 8 x 8 to store each data. Only an external register is used to segment the current settings for each led. A simple four-wire serial interface can be connected with all general microprocessor. Each data can address does not need to rewrite all display update. Max7219 also allows the user to select each data coding or non-coding. Low power consumption shutdown mode the device contains: A 150 and #x3bc; an analog and digital brightness control, a limited scan register allows the user to display 1-8 data, there is a let all led luminescence detection mode. Only 3 io port can drive 1 dot matrix! dot matrix display without blinking! support cascading!.
MAX7219 Dot Led Matrix Module is a serial input common-cathode driver that interfaces microcontroller to LED matrices. All common micro-controllers can be connected to this module by using a 4-wire serial interface. Each output can be addressed without refreshing the entire display. This module requires only 3 I/O lines for driving the display, making it ideal for your microcontroller projects. Only one external register is used to set the segment current of each LED.
Dot LED Module to the Arduino
Vcc – 5V
GND – GND
DIN – Pin 12
CS – Pin 10
CLK – Pin 11
- Requires only 3 communication wires of MCU
- Cascading multiple Matrix LED Module is very easy
- Size of the display is very compact
- The PCB features M3 holes for mounting.

1 x Dot LED Matrix Module
1 x Connecting Wire
The product is highly durable and worth the price.Robot Banao is the perfect place to purchase robotic materials at a better price
works good with my arduino uno.Is it compatible with NodeMcU.
The media could not be loaded. Â Works, no problems whatsoever
