1Pc MAX7219 Dot Matrix Module 4-in-1 LED Display Module for MCU Control
- MAX7219 4-in-1 Red Dot Matrix Module: This display module is built with the MAX7219 serial LED driver and combines four 8×8 common-cathode red LED matrices, making it ideal for scrolling text, numbers, symbols, patterns, and simple animation displays.; Drives 8x8 Common-Cathode LED Matrix: Each MAX7219 driver can control one 8x8 common-cathode dot matrix. The chip includes scan circuitry, segment drivers, and internal 8x8 static RAM, allowing stable and efficient LED matrix display control.; Simple Four-Wire Serial Interface: The module uses a convenient four-wire serial interface for easy connection to common microprocessors and microcontrollers. It requires only a few I/O pins, making it suitable for Arduino, STM32, 51 MCU, ARM, and other embedded platforms.; Adjustable Brightness and Low-Power Shutdown: The MAX7219 supports both analog and digital brightness control, a scan-limit register, display test mode, and a low-power shutdown mode of approximately 150 A, helping users customize brightness and reduce power consumption when needed.; Cascadable Design for Extended Displays: With input and output interfaces, multiple modules can be cascaded to create longer LED displays. The 5V module measures approximately 132 x 33 x 13 mm and includes 3 mm mounting holes for easy installation in DIY clocks, message boards, scoreboards, and prototype projects.
