We recommend industrial grade SD cards, but any SD card can be used up to 128GB. The SD card needs to be formatted with an ext3 file system with a minimum cluster size of 4KB. Typically, on Windows systems you will need to use an external software tool to format to an ext3 file system. A software tool that we have tested successfully for this task is EaseUS Partition Master.

What’s the definition of an Industrial grade SD Card?

I’m not sure if there is an official definition or standard like there are for speed ratings, but it’s more about quality and dependability as this article explains.
