DIYables Dot Matrix Display FC16 4-in-1 32x4 LED for Arduino, ESP32, ESP8266, Raspberry Pi
Click to zoom
Quick Overview
This DIYables 32x8 LED dot matrix display module integrates four 8x8 matrices into one horizontal unit, creating a 256-LED scrolling display controlled by MAX7219 driver ICs (FC-16 model). It's ideal for marquee text, tickers, clocks, and notification displays in Arduino, ESP32, ESP8266, and Raspberry Pi projects.
The MAX7219 drivers handle all LED multiplexing and brightness control via a simple SPI interface (VCC, GND, DIN, CS, CLK), eliminating complex wiring and the need for external resistors. The module can be daisy-chained with additional units to create even wider displays.
Measuring 12.8 cm x 3.2 cm, this compact horizontal module fits breadboards and project enclosures easily. It works with both 5V and 3.3V microcontrollers, and popular libraries like MD_MAX72XX and LedControl simplify programming for scrolling text and animations.
