I accidentally purchased this. I have confirmed that it works, but please understand that it is a used item. The wireless module connects to your Osmo Pocket and your mobile device via Bluetooth or Wi-Fi, allowing for seamless remote control and more flexible shooting. It also serves as a base for placing the Osmo Pocket on a flat surface. Furthermore, you can charge the Osmo Pocket via the USB-C port.
