MAX7219 Dot Matrix LED Display Module (Single Digit / 8×8 Matrix)

Description

Product Overview

The MAX7219 8×8 Dot Matrix LED Display Module is an easy-to-use, single-digit display solution perfect for Arduino, Raspberry Pi, and other microcontrollers. Powered by the popular MAX7219 serial driver IC, this module allows you to control 64 individual LEDs simultaneously using only 3 data pins. [1, 2, 3, 4, 5]

Whether you are building a digital clock, a scrolling text marquee, or an interactive DIY electronics project, this compact 8×8 matrix module eliminates complex multiplexing code and messy wiring. [1, 2, 3]

Key Features

• • Efficient Serial Interface: Uses a 3-wire SPI-compatible interface (DIN, CS, CLK) to save valuable microcontroller pins.
  • Integrated Driver: The onboard MAX7219 chip handles all LED multiplexing, refreshing, and current control automatically.
  • Adjustable Brightness: Features both digital and analog intensity controls, easily adjustable via software.
  • Cascadable Design: Input and output pins allow you to chain multiple 8×8 matrix modules together to form larger displays.
  • Solderless Setup: Pre-fitted with header pins for quick breadboard prototyping or jumper wire connections. [1, 2, 3, 4, 5]
