The Usage of the USB Port on the DJI Smart Controller

The USB A port located on the back of the DJI Smart Controller has several potential uses:

1. 4G Dongle Compatibility: The USB-A port can be used to connect a 4G dongle to the controller. This allows users to establish a mobile data connection and access online services or features that require an internet connection.
2. Support for USB SD Card Readers: The USB-A port is also compatible with USB SD card readers. By connecting a card reader to the port, users can easily transfer files and access media stored on SD cards.
3. Limitations with USB SSD: It is important to note that the USB-A port may not recognize USB SSDs (Solid State Drives). This limitation may be due to the size limitation of the controller, which supports a maximum of 128GB card size.

The Functionality of the SD Card Slot in the DJI RC Controller

The SD card slot found in the DJI RC controller offers the following functionality:

1. Previewing Captured Media: The microSD card slot allows users to preview copies of the photos and videos that have been captured using the DJI Mini 3 Pro drone. It provides a convenient method for reviewing and selecting desired media files.
2. High-Quality Recording on DJI Mini 3 Pro: While the microSD card placed directly on the DJI Mini 3 Pro drone saves and records all photos and video clips in high quality, the SD card slot in the controller serves as a secondary storage option. It allows users to view and manage their captured media without the need to remove the microSD card from the drone.

Useful Tips and Considerations

• When inserting a microSD card into the Host Port or SD card slot, ensure it is securely inserted to prevent data loss or damage to the card.
• Consider purchasing the DJI Cellular Dongle if you require cellular connectivity for your DJI RC controller.
• When using the USB-A port, make sure to select compatible accessories such as 4G dongles or USB SD card readers.
• If you encounter issues with a USB SSD not being recognized, take note of the size of the drive as there may be a limitation on the maximum supported card size.

Conclusion

Understanding the functionality of the host port, USB port, and SD card slot on the DJI RC controller allows users to take full advantage of the controller's capabilities. Whether it's expanding storage capacity, accessing online features through a 4G dongle, or transferring files using USB SD card readers, these ports provide convenient options for enhancing the overall user experience. Remember to follow the recommended guidelines and consider the compatibility of accessories for smooth operation.
