MAX7219 Dot Led Matrix Module MCU Control LED Display Module for Arduino ARM Rasberry

Working Perfectly

While writing the dimensions of a product company should write Product dimensions not the package dimensions. Why the hell we should care about the packaging. I took this product because of the dimensions of 4" - 8" but I received product of 1.5" x 1.5" display.And the best part was.... it's non-returnable.

The product is awesome perfectly soldered, good intensity of light, they included female to female connectors which is suited for an Arduino nano, but frankly speaking, I'd like a female to male connector as it is more convenient to use the product via a breadboard, anyways we get the connectors for very cheap so no worries, this product is awesome

This supports my arduino nano, arduino uno and arduino mega flawlessly. Strong built and a good product to have for my projects and other customizations. It is just like plug and play so, there's no problem or difficulty using it. It is carefully soldered. 5 star from me.

Very good product. However, I purchased this from two different sources (Amazon and another) and now the light quality (brightness, colour etc) of these two are not matching. You have to be aware of this and order just one lot from any seller. No issues with Amazon or the product though.

Good product

Excellent product, working very well.

Good one. It has SPI interface, which made the job easier. It took just a few minutes to connect to Raspberry Pi and drive through readily available python library.
