After stumbling to Brian's tutorials page showing how easy it was to wire a NodeMCU to a 64x32 led matrix I had to give it a try. My mess of jumper wires worked for a testing but was too fragile. PCB design is my full time job so I designed a single board that plugs into the back of the display making it far more portable using no wires or cables at all.
Check out http://www.instructables.com/id/RGB-LED-Matrix-With-an-ESP8266/ for all the details like wire diagram and Arduino library.
