SD card setup



Flipper Zero stores keys, remotes, and cards on a microSD card, as well as databases which is why it is important to insert the microSD card BEFORE updating the firmware. Flipper Zero uses the FAT32 file system and supports microSD cards up to 128 GB, but we recommend using a microSD card with a maximum capacity of 16 GB or 32 GB.

You may need to format the card after installing a new microSD card if the file system was not recognized. To do this, follow the steps below:

1. Open the menu :ok:OK.
2. Select Settings.
3. Open Storage.
4. Choose Format SD Card.
5. The next window will warn you that all data will be deleted after formatting. Ignore it and press :right:RIGHT to continue.
6. When finished, you will see: Format complete!

To check speed of the microSD card inserted into Flipper Zero, follow these steps:

1. Open the menu.
2. Select Settings.
3. Open Storage.
4. Select Benchmark SD Card.

When complete, the results will be displayed:

Each line has the following form: 1b: W 6K R 6K where:

• 1b: — is the size of the block for which testing took place. 1b — 1 bit, 8b — 8 bit.
• W 6K — write speed in kilobits.
• R 6K — reading speed in kilobits.

Safely ejecting the microSD card stops all writing and reading processes, avoiding data corruption on the card during removal or replacement.

To unmount:

1. Open menu.
2. Select Settings.
3. Open Storage.
4. Select Unmount.
5. Confirm by pressing the :right:RIGHT.
6. Remove the memory card from the device.
