A 4x12 matrix using 3 modular 4x4 matrix boards and powered by a Pro Micro.
this one is using a Pro Micro. The Pro Micro has less data pins available so only 3 boards can be connected instead of 4. There are 2 pins left over, I used one (B5) for a backlight circuit like on a Gherkin. The other data pin (B4) is left for possible use with a WS2812B strip.
