Description

This display PCB is using the MAX7219 display chip. The big display is Chip 0 (Led0-4), the two little ones are Chip 1 (Led0-4 then 5-7 of the 8 displays, so adjust your code accordingly.) You will receive the board and the SMT components already soldered in. NO DISPLAYS. With all the colors out there, I’ll leave that up to you to order (Ebay/Amazon are good sources. .36 for the small ones, .56 for the large one. Common-Cathode). The boards support daisy chaining, I have 5 running on my arduino, but make sure you provide adequate power or the the Max7219 will act up.
