These are really nice to add a little color to your projects! You'll have to do a little search online to get the schematics etc. However, that takes less than 5 minutes for you to find an acceptable library to drive it. Works well with digital and analog coding commands! The 8x8 matrix is prefect for displaying single letters and numbers in your project. Excellent brightness too! So far, so good!

I have come to review these microprocessor accessories by how easy they are to get up and running. These 8x8 matrix displays are very simple to operate, and I was able to get it working very easily with an Arduino Uno using readily available libraries. The LED matrices come with a detachable driver board with the MAX7219 driver, as well as some straight and right-angle headers that you can solder yourself. You can also daisy chain them if needed. Just a great, simple little accessory for your microcontrollers, and very easy to get up and running. 5 Stars!

Filter capacitor is missing, the board can become unstable when connected to another one.Just solder 10-100uF capacitor between VCC and GND
