@user81779, are you still pursuing this project? Test setup in conversation about Driving LED matrix with shift registers such as 74HC595 has validated that such LED modules can be connected to Espruino. Furthermore, it has shown that Espruinos Graphics libarary can be used to easily control color, write text in various fonts, set pixels, draw lines, shapes - hallow and filled - and more.
