The used Insta360 ONE R Core Module is the brain of the modular ONE R action camera system.
It mounts side by side with a lens module on the battery base module, both sold separately, and it provides a touchscreen live view display. The core is also where an up to 256GB microSD card for the ONE R system goes, also sold separately. It also supports the optional ONE R 3.5mm Mic Adapter via a USB Type-C interface, which is next to the microSD card port on the side of the module behind a door cover. Besides a live view, the display of the core module shows the remaining battery time and provides access to the settings of the ONE R system.
