The 4-in-1 Dot Matrix LED Display combines four 8×8 red LED matrix modules into a single unit with the built-in MAX7219 driver chip. With 256 individually addressable LEDs under a single board, it’s ideal for scrolling text, animations, clock displays or dynamic sensor information in your TechBox projects. What’s Included: 4-in-1 Dot Matrix LED Display Module (red, 256 LEDs) – Pre-assembled 4×(8×8) matrix board with MAX7219 driver chip. Pre-soldered Breadboard Pins – Standard male header pins included for quick breadboard or jumper-wire connection. Display & Driver Features: 256 Red LEDs – Four contiguous 8×8 red LED matrices act as one large 32×8 display for smooth scrolling and graphics. MAX7219 Driver Chip Embedded – Simplifies connections and controls the LED brightness, multiplexing and wiring. Minimal Wiring – Requires only 5 pins (VCC, GND, DIN, CS, CLK) for full control of the display — ideal for microcontroller projects. Ideal for Animations and Text – Easily scroll messages, show temperature/humidity values, create timers or display student-designed graphics in the classroom. Breadboard-Friendly – Standard header pins allow plug-and-play setups with your Nano Board or other microcontroller kits. Product Dimensions: (x1) – Approx. 3.2″ L × 1.0″ W × 0.3″ D (≈ 80 × 25 × 8 mm) Weight: Approx. 0.6 oz (≈ 17 g)
