Which microSD cards can I use with a BitBox02?

  • You can use normal microSD cards of type SDHC with your BitBox02. 
  • MicroSD cards of type SDXC are not supported.
  • The capacity of the microSD card does not matter, the backup file is very small so just get the lowest capacity available.
  • We recommend going for microSD cards from a quality brand such as Sandisk or Transcend.


  • If not done by default, you should be format it using MS-DOS (FAT) or vFAT for its format.
  • After you have formatted the microSD card, never plug it into your computer again, only into a BitBox02. 
We recommend to verify your backup every couple of months.
