These are actually very good when you fully understand what they were intended for. They are intended as individual letters for a sign. That is why there are not enough led's to actually fill the board of 49 positions, there are only 40 led's supplied. I have not assembled it yet so can't comment on how good it actually is.For the full instructions on how to assemble this look on here https://www.icstation.com/simple-breathing-lamp-redgreenyellow-customize-matrix-display-module-p-14803.html The only two things that you actually need to know to assemble it is that the rectangular pad connects to the shortest LED pin.The pins of other LED are inserted into the corresponding pads in sequence. The other is the little square switch needs to go with the little ribs on the switch facing down towards S1. Everything else is self explanatory.

LEDs insuficientes para serem concluídos, mas geralmente agradáveis

Insufficient LED's to complete but overall enjoyable

Muito divertido. Gostei que não houvesse instruções. Nem mesmo chinês. Funciona muito bem. O kit não tinha 10 LEDs. Pedi mais chumbos catódicos comuns de 5mm para preencher a matriz. Espero que tenha testado correctamente e não é suposto serem do tipo ânodo comum.

Lots of fun. I liked that there were absolutely no instructions. Not even Chinese. It works great. Kit came short 10 leds. I ordered more 5mm common cathode leds to fill out the matrix. Hope i tested correctly and they aren't supposed to be common anode type.
