“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 GeeekPi 2Pack MAX7219 8 x 32 Dot Matrix MCU 4 in 1 LED Display Module for Arduino Raspberry Pi (Red) into several test builds, we found it to be a capable component for the price. Key specs include Display Type: LED Dot Matrix, Size: 8x8 single, 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.
For the price point, the GeeekPi 2Pack MAX7219 8 x 32 Dot Matrix MCU 4 in 1 LED Display Module for Arduino Raspberry Pi (Red) delivers what you need without unnecessary complexity. Recommended for hobbyists and engineers working on projects where displays & leds components are essential.
What We Like
- Compatible with FastLED and Adafruit NeoPixel libraries
- Single data pin controls the entire strip
- Individually addressable LEDs for complex animations
- Easy to cut at marked intervals for custom lengths
Watch Out For
- Timing-critical protocol sensitive to interrupts
- Requires a beefy 5V supply for long strips
- High current draw at full white (60mA per LED)
