Use this SmallRig HDMI and USB Adapter for BMPCC 6K Pro to attach HDMI and USB Type-C cables to your camera and route them to the back instead of the side.

This makes for a much neater setup and helps prevent the cables from interfering with other accessories.

You can attach the cables to the adapter and the adapter to the camera. An included Allen wrench enables you to tighten the thumbscrew, holding the adapter fast to the camera.
