I have 18 of the 8x8 LED matrices that are row-anode column-cathode part number 1088BS.
I bought them before the Chinese started selling the pcb with MAX7219 and 8x8 LED matrix all-in-one which makes it a lot simpler cascading the LED matrices.
Is there a ready-made PCB that I can buy and use with these type of LED matrices? If so, where can I buy some? And if so, what Arduino library would I then use?
I hate having to toss them, but I am not interested in spending the time wiring+soldering the parts together.
