The DJI Osmo Pocket Expansion Kit provides a few add-on accessories that will let you do a lot more with your Osmo Pocket Gimbal. The Controller Wheel attaches right below the LCD of the gimbal, facing the user, and provides a dial for precise pan and tilt control. The dial is comfortably accessible by thumb. A selector switch next to the dial allows you to choose whether the dial should control pan or tilt motion. There's also a button for changing shooting modes and another button for re-centering the gimbal. The Wireless Module allows for remote control of the gimbal from your mobile device. It does this by providing a wireless connection between the two over Bluetooth and Wi-Fi while serving as a base. It can also be used just as a base. And it offers a USB-C connector for charging the gimbal. The Accessory Mount provides a 2-prong mount for attaching 3-prong accessories on the front of the gimbal. It clasps on around the center of the gimbal.
