Hi limel!.
Firs of all, sorry for my English.
Could you manage the matrix with success?
Here in spain the adafruit are very expensive and i don't need colors. This matrix is ideal for me.
In your last link, i can see a better libraries with drawPoint, drawrect and drawimage functions but the product is diferent, only 16x32 matrix. it worked for "canton electronics" 16x64 display?
Can you scroll text?
