  • SD, SDHC, and SDXC Memory cards that are compliant with the SD Association (most all commercially available cards) are properly pre-formatted and are ready to use in AirStash A02.
  • AirStash firmware 3.1.1 and later support ExFAT, FAT32 and FAT16. AirStash firmware 3.1.0 and earlier support FAT16 and FAT32 formats.

Formatting your SD Card

  • AirStash Firmware 3.1.1 and later (current): With firmware 3.1.1+, the 4GB file size limit on AirStash is removed. This is automatic when using memory cards 64GB and larger.    You can reformat your SD Card to accept the larger files by following the instructions on this link, but selecting ExFAT instead of FAT for the format type -
  • Older AirStash Firmware 3.1.0 and earlier:  Please format the memory card using the instructions here: .  However, we do recommend a firmware upgrade to be able to take advantage of larger SD Cards and also to get all the latest AirStash features. 

Firmware upgrade

We always recommend upgrading to the latest firmware. This will allow you to take full advantage of the larger SD cards, which accept files larger than 4G, and gives you the most up-to-date features in the AirStash.   The upgrade files and instructions are available here :  Always perform a firmware upgrade of your AirStash to 3.1.1+ using a known working card.
