Review on GeeekPi 2Pack MAX7219 8x32 Dot Matrix MCU 4-in-1 LED Display Module for Arduino & Raspberry Pi - Red Color by Lisa Jones

Revainrating 4 out of 5

Inverted text Arduino

These modules work great and are very affordable. BUT, if you use them with Arduino and the popular MD_PAROLA library, you have to be aware that the hardware settings have to be adjusted. In the example sketches for the Parola library, see the line #define HARDWARE_TYPE MD_MAX72XX::PAROLA_HW. Replace "PAROLA_HW" with "FC16_HW" for this display to work properly. It took an hour to dig into google to figure it out, five stars otherwise.

Pros
  • Computer and Accessories
Cons
  • The list is getting long.
