* Both the circuit and the leds feel solid
* It works properly, and is quite bright
* Datasheet is very easy to come by online
* The connectors from the board to the led are slightly slanted. It works well anyway.
I'd say that this is a reasonable price for this module. The chip is MAX7219 which can be used with the arduino board. I used the library called "LedControlMS" link in instructables.com. The library allow you to cascade multiple of this module to create a cool moving text display. Arrived in ... Read more
The module was packed in bubble plastic to prevent damage during shipment. Module is complete an works at onze. Use one of the examples from internet and it works. Use just 5 lines and some coding and you have an animated display As far as I can see none. If you have more than 1 unit connecting them ... Read more
Completed and ready to use LED matrix module. I am fully satisfied with it. I was able to run it at the very first time. I bought two of these modules and they can be connected into cascade. Both modules are working perfectly. Soldering seems to be OK. I would not be able to do it better... :) I do not ... Read more
Thanks to readily available libraries and examples for the MAX7219 chip, this matrix was very easy to use. I was able to cascade two matrices. I don't see any reason why more won't work. Probably willl need to add power supply after 3 or 4. The supplied wire is great for cascading multiple matrices, ... Read more
- It is inexpensive, compared to the real MAX7219 - it Works with Arduino using the MAX7219/7221 libraries - there are plenty of libraries to choose from - it takes the hassle of assembling the board from your hands (which is a little troublesome, since there would be a lot of cables) - it is easier ...

Really handy little modules to have around. They're easy to drive from an Arduino using the LedControl library which comes with a useful example for testing your modules. MAX7219 IC is very well known, widely supported and very easy to drive. Grab a few modules so you can chain them together to display ... Read more
Even though it's a bit more expensive than the parts them self, the fact that you receive a pre-made and tested module of good quality may prove more advantageous. The board itself contains the LED matrix, the 2 capacitors critical for correct operation, and the MAX7219 IC in a IC holder. It may prove ... Read more
Compact, works fine with Arduino, bright, perfect for prototyping ! Only male connectors : it would have been great to have female too, to be able to chain them and mount them close : I have now to unsolder pin to attach two displays together.... Or I would have prefer to have the pins on the other sides ... Read more
