I am looking to start a school project whereby we create a board display, daisy chaining two 64 x 32 LED boards. A brief look at your promo video suggested “scanning issues” related to the amount of Megahertz required. We would also like to use raspberry pi’s to look after the software side of things. Is there a forum or project link to this particular issue? You never know I could bring Times Square to my classroom. 
Hi,
Could you provide the product code or a link to the product in question ?
Regards,
