Hi,

I was wondering if it is possible to use more than one of the Grove 8x8 RGB Matrix with a single Arduino. I bought 4 of them in order to create an 8x32 display. If it is possible how would I go about doing it? Any help appreciated.

If it is software I2C is ok. It depends on how much GPIO you have. @CodeSmith

I want to do the same thing. I have a base shield on an arduino uno, with 3 led Matrix. How can I set the display in 8x24 ?

were you able to figure out how to interface multiple matrices?

You can use I2C multiplexer.
