Does anyone know of the minimum memory size, maximum memory size, and class that you need to use a microSD card with the Arduino Yun? I couldn't find any information on the limits. I can see the FAQ on the microSD cards for the Yun [Arduino Playground - Yun] but it doesn't provide any information about the size requirements. Any help would be appreciated.
Someone please correct me if I'm mistaken, but from what I've read the card reader supports the SD specification up to version 2.0 (SDHC). So any SDSC or SDHC (but not SDXC) card from 1 MB to 32 GB in size should work.
In case you're interested, some more info:
The Yun's schematic & reference design indicates that the AU6350 is the card reader:
The AU6350 from Alcor Micro supports the SD specification up to version 2.0 (SDHC):
