Max7219 Dot Matrix Module for Arduino-AR-151-D
Out of stock
The MAX7219 LED driver can be used to control 7-segment displays up to 8 digits, bar-graph displays, or 64 individual LEDs. The driver communicates with the Arduino through SPI so you only need three wires to control the display.Since the MAX7219 can control a maximum of 64 LEDs, the maximum size dot matrix display it can drive is 8×8 pixels. However, you can daisy chain multiple drivers and matrices together and easily control much larger displays like 8×32, 8×64, or even bigger. Still, you only need three wires to control all of the ICs so you need very few I/O pins of the Arduino.
