Banggood

Bem embalado. Conforme descrito.

i use it on a arduino with the mblock software and it is vere easy to use. you can choose each led to turn on or off and the luminosity . It come with dupont cable to connect to the arduino

I use it with an arduino. I program the arduino with mblock and there is a plugin to use MAX7219 easyly. You just have to choose the led you want to power by sekecting row and column. Great for kids learning to program.

OK

I ordered two of these displays together upon arriving one worked as intended but the MAX7219 chip on the second display was seated incorrectly and will require re-soldering manually to work as intended. See chip on the left in the image.

little bit of a pain to program, but it works well and I have had no problems with it so far.

I need additional display like this one. It is OK.

can't wait to use this on my projects .. have to test it first

the packaging it came in was nice.

it works perfectly, early delivery, thank you.
