For users who prefer a local solution, we provide a dedicated Desktop App. This setup does not require any accounts or cloud services — all data is stored locally.
We support SD card insertion, replacement, capacity expansion, and batch image import. After importing images via SD card, actions such as changing displayed images, managing playlists, or modifying Wi-Fi settings still require the desktop app.
⚠️ Important: For most users, manual SD card handling is not necessary, regardless of whether you use the mobile app or desktop app. If there is no special requirement, we recommend not operating the SD card directly.
SD Card Insertion, Removal & Replacement
When the SD card is removed, the device will not be able to change images. Any image upload or display action will fail.
If the device restarts without an SD card inserted (for example, manual sleep/wake or automatic wake), it will display the initial QR code screen.
After reinserting the SD card, please use a pin to press the reset button on the back of the device to force a reboot and ensure the SD card is properly read.
Replacing the SD Card
If you plan to use a different SD card, format it to FAT32 before inserting it into the device.
After insertion, please use a pin to press the reset button on the back of the device to force a reboot and ensure the SD card is properly read.
The maximum supported SD card capacity is 32GB.
Batch Importing Images to the SD Card
Displaying Images & Managing Playlists
Please download and install the Desktop App, then follow the instructions within the app to:

Note: The first time the desktop app loads images from the SD card, it may take longer than usual. Please be patient.
