The USB-C port on iPad Pro allows connections to a variety of devices. For example, you can connect a digital camera or the Apple USB-C to SD Card Reader to import photos to your iPad Pro. Other USB devices you can connect to iPad Pro include these:
- Hubs and docks
- Keyboards
- Audio interfaces and MIDI devices
- External storage devices to import photos and videos
- USB to Ethernet adapters
Depending on the device, you might need an adapter. Here are some common connections:
- If the device that you're connecting to has a USB-C port, all you need is a cable with USB-C connectors on each end, such as the cable that came with iPad Pro.
- If the device has a USB-C connector, you can plug it directly into the iPad Pro USB-C port.
- If the device has a USB-A connector, you can plug it into the Apple USB-C to USB adapter, then plug the adapter into the iPad Pro USB-C port.
