3 multiple matrix boards: If you want to cascading connect multiple  matrix boards, please connect CN2-out pin of the first board to CN1-in pin of next board. Make sure  VCC of two boards should be connected and  so do the gound pins. 2 Download Sample code from following link osoyoo.com/driver/16X16matrix.zip Unzip above file  and load the code into Arduino IDe. you can display motion and static graphs on the matrix boards. The codes are quite straight forward, you can change the display content in the code and customize your own graphics. 1 videohttp://osoyoo.com/driver/arduino10.gif http://osoyoo.com/driver/arduiino_11.gif others: parts connection graph:16-16 chip data sheet:74HC138   74HC595
