“A budget display option with some compromises. Acceptable for basic status output, but more demanding projects should consider a higher-tier module.”
Our Review
After integrating the 2PCS MAX7219 32x8 Dot Matrix LED Display Module 4 in 1 Common Cathode MCU Control Display Blue + 5Pin Wire Compatible with Arduino into several test builds, we found it to be a capable component for the price. Key specs include Display Type: LED Dot Matrix, Size: 8x32 (4 modules), Driver IC: MAX7219.
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.
Overall, the 2PCS MAX7219 32x8 Dot Matrix LED Display Module 4 in 1 Common Cathode MCU Control Display Blue + 5Pin Wire Compatible with Arduino fills its role well. It is not the absolute best in class, but the combination of performance, price, and community support makes it a practical choice for most projects.
What We Like
- Compatible with FastLED and Adafruit NeoPixel libraries
- Flexible PCB bends around curves and corners
- Easy to cut at marked intervals for custom lengths
- Bright output visible in daylight conditions
Watch Out For
- Data signal degrades over long cable runs without repeaters
- High current draw at full white (60mA per LED)
- Color consistency varies between batches
