Yes! You can use the D3 directly with any iPad that has a USB type C port, using a type C to B USB cable, or with a type C to A adapter, and the included USB A to B cable.
For an iOS device that uses a lightning port, like iPhones, iPod Touch, or older iPads, you will need an Apple USB 3 camera adapter. iOS devices that use a lightning port limit the amount of power a USB accessory can draw, so it will be necessary for the device to be charging to use the D3. With the USB 3 adapter, you'll be able to connect the D3 to the USB A port on the adapter as well as an appropriate charger for your device. We recommend using Apples USB fast charger for the best results.
