Package Contents: 1pcs 5MP motorized focus camera module, 2pcs flex ribbon cables (15cm/100cm) for Raspberry Pi A&B series, and manuals. A Long Cable: 100cm/3.28ft extension cable included, long enough for mounting the camera, especially useful when you don’t want to place the camera near the Raspberry Pi. Focus Controllable: A camera focus control plugin has been developed to control an Arducam motorized focus camera using the OctoPrint Control tab, which utilizes custom commands from your slicer to adjust focus while printing. Motorized Focus: See closer and easier than the fixed focus (1 m to infinity) lens, the minimum focal length is about 5CM, which is better to monitor the 3D printer nozzle and make you pay close attention to your creation. Hassle Free: Works as a native Raspberry Pi camera on Raspberry Pi 4/3B+/3 and more, and Arducam has solved the problems with the installation and setup on OctoPi. NOTE: Before using the camera normally, you need to do some simple script configuration to make the camera work!.
