Sobre este producto
- Hardware Overview: Each MAX7219 module controls an 8x8 LED matrix (5V logic) with built-in decoding, eliminating external resistors/drivers. SPI Control Protocol: Cascading Support: Connect modules via DOUT→DIN for extended displays (CLK/CS shared across all units) Refresh Rate: 800Hz scan rate via 16MHz SPI clock for flicker-free animations Mechanical Design: Dimensions: 32×32×15mm (1.26"×1.26"×0.6") Mounting: 4× M3 screw holes (corner-to-corner 28mm spacing) I/O Ports: Gold-plated headers (input/output marked for error-proof chaining) Software Integration: Pre-tested with LedControl (Arduino) and luma.led_matrix (RPi) libraries; sample code provided for: Scrolling ASCII text (32+ characters across 3 modules) Real-time sensor data visualization (temperature/clock) Pixel-art animations (8-bit game emulators) Power Management: Voltage Regulation: Onboard 5V regulator stabilizes input (6-12V tolerant) Current Control: Adjust brightness via 16-step PWM (0x00-0x0F register) Applications: Retro gaming consoles (Pong/Tetris clones) Public transport info boards Factory machine status indicators Package Includes: 3 × MAX7219 LED modules + pinout diagram (1.5m ribbon cable recommended for cascading). Technical Specs: LED Type: 5mm Red Common Cathode View Angle: 120° horizontal/vertical Operating Temp: -20℃~70℃ Safety Note: Add 220Ω resistors per matrix segment if exceeding 5V input. Avoid static discharge during handling.
