Maxim 7219 single color matrix displays
[1]
There are several modules with this chip and the matrix itself for example the FC-16, which either comes with a single 8x8 matrix or 4 of these combined together forming a 64x8 matrix display.
A library that can be used to jumpstart the development is the MD_MAX72XX library and for animations and scrolling the MD_Parola library can be easily used.
