4 Way MAX7219 dot matrix moving message display module for arduino esp8266, UK s

4 Way MAX7219 dot matrix moving message display module for arduino and esp8266 not included. These modules can be used to construct a moving message display. They can be cascaded together to make longer displays. I have a library that can be used with this module as the MaxMatrix library is unable to rotate the display. These modules have the advantage in that you can create a moving message display without all the messy wiring between modules. 

The Library can be found here https://github.com/iotmodules/fourMatrix.git
