HiLetgo 3pcs MAX7219 8x8 Dot Matrix LED Display Module 5V MCU Control MAX7219 8 * 8 LED Dot Matrix DIY Kit

They work fantastic, though learning how to use them was a fun challenge. Went from not knowing why the lights wouldn't turn on to getting a Pong game running 5 hours later haha

Good. In my experimentation.Brightness is across the board. Not pixel per pixel. Did what I needed! Easy to work with.

Overall, I'd say it's definitely worth the price. The only thing I wish is that they offered different colors like Adafruit does, and it is not worth the shipping costs to get it from their site and here. The board can be a bit glitchy if mishandled (I used an attiny85 and had a bit loose connection, making me need to cut power from the display and turn it back on) but if used as intended it should work perfectly fine.

all 3 worked great, good for kids learning coding

Poor / uneven soldering jobs on each circuit board make them impossible to line up for any kind of display incorporating multiple panels. Junk went into the garbage within 5 minutes of its arrival.

One of the three didn't work, but the others did alright. Surprisingly bright when on all the way (hard to look at). Would have been nice to have all three functional.

Unfortunately, the order did not include the headers in the sealed envelops. Also, they were shipped in a zip lock bag so the order did not include the box and instruction leaflet that was illustrated in the advertisement. I will return them since they are not useful without the headers.

It worked great for the application I was using it for. Soldering can be seen as a plus or minus depending on if that is something you want to learn and/or have time for. Once soldered it works great with the ledcontrol.h library in Arduino.
