Re: Use arduino and adafruit grand central sd card
In theory, yes. But it is risky and would involve some coding to coordinate access between the two boards.
You would need to make sure that all of the SPI pins on the Grand Central were set to high- impedance mode when the Uno was accessing the card. And you would need to do the same on the Uno when the Grand Central was accessing the card. Otherwise you would likely damage one or both processor boards.
