This is great for scrolling text and graphics. I received a slightly different display compared with blue PCB and no jumpers. It's cool that you can remove each matrix to replace them. As with previous reviews, it took a little while to figure out but in my case I also had to use this library https://github.com/MajicDesigns/MD_MAX72XX and in the example scripts change MD_MAX72XX::PAROLA_HW to MD_MAX72XX::ICSTATION_HW and MAX_DEVICES to 4 and use pins 14 (CLK_PIN), 13 (DATA_PIN), 15 (CS_PIN)
