# PX4 SD Card Layout
|
|
|
|
The PX4 SD Card is used for storing configuration files, flight logs, mission information etc.
|
|
|
|
:::tip
|
|
The SD card should be FAT32 formatted for use with PX4 (this is the default for SD cards).
|
|
We recommend that you reformat cards that are using a different file system.
