Good product. Very fast shipment. It works extremely bright.

Gostei muito de ter conseguido montar essa Matrix de LEDs 16x32. É uma ótima ferramenta para aperfeiçoar os conhecimentos em soldagem de componentes eletrônicos. Recomendo a todos que gostam de eletrônica e principalmente Arduíno. Gravei dois vídeos, um sobre a montagem e outro do teste de funcionamento: VÍDEO 01: https://youtu.be/T8xXpCghs50 VÍDEO 02: https://youtu.be/3T640QICZdc

At less than $13, this 16x32 dual color LED matrix is a great deal. However, there does not seem to be any documentation on the product page. No assembly instructions, no circuit diagram, no example code. :-( I would not recommend this as your first surface mount soldering kit, there is a lot of soldering involved here. As I mention in my video, with proper tools, it is not as difficult as it looks. And I found an instructable for a similar circuit that includes an Arduino library compatible with this kit (linked in video description of part 2) Part1: https://www.youtube.com/watch?v=RjCNQ3td91k Part2: https://www.youtube.com/watch?v=-oqwJL8Lb2M
