The device will **not** be able to work properly without a microSD card.
The card of up to 256 GB is needed to store any data (e.g. keys, cards, remotes, databases). A 4 GB one should be
sufficient to store all the necessary data.
The Flipper Zero may take longer to recognize a microSD card with a higher storage capacity.
The device uses a slow, energy-efficient SPI interface that can read data at almost 600 KiB/s, which is sufficient for
it's tasks.
Update the device via the _Flipper Mobile_ app or _qFlipper_.
Setup
```sh
curl -o 'qFlipper.AppImage' 'https://update.flipperzero.one/builds/qFlipper/1.3.3/qFlipper-x86_64-1.3.3.AppImage'
