Our Review
For $19.00 CAD, the MAX7219 LED Dot Matrix Module, 2-Pack Microcontroller Display Modules with Connection Cables packs respectable specs: Display Type: LED Dot Matrix, Size: 8x8 dual, Driver IC: MAX7219. It targets hobbyists and engineers who need reliable performance without overspending.
Display quality was impressive. Each LED is individually addressable and the colors are vibrant. FastLED and NeoPixel libraries make animation coding straightforward.
Integration with Arduino and ESP32 was hassle-free. Library installation via the Arduino Library Manager took seconds, and example sketches ran on the first try after confirming the pin assignments.
The MAX7219 LED Dot Matrix Module, 2-Pack Microcontroller Display Modules with Connection Cables earns its place in the parts bin. Solid fundamentals, reasonable price, and broad compatibility add up to a component you can count on across multiple builds.
What We Like
- Easy to cut at marked intervals for custom lengths
- Single data pin controls the entire strip
- Bright output visible in daylight conditions
- Individually addressable LEDs for complex animations
Watch Out For
- High current draw at full white (60mA per LED)
- Color consistency varies between batches
- Data signal degrades over long cable runs without repeaters
