The Libretech ALL-H3-CC is compatible with the Orange Pi's camera sensor module. This module itself features a detachable camera sensor module ribbon connector, which is populated with a GC2035 sensor by default. The connector is also compatible with Bananapi's HDF5640 camera module, which features an OV5640 sensor. The Orange Pi module however does not activate the auto focus feature of the HDF5640 module. Enable the camera by enabling the CSI controller, I2C control bus, and adding needed regulator supplies. As the schematics for the module are not available, the regulators and GPIO lines controlling them are just an educated guess.
