Dear buyers, based on the messages of some customers during this period, we learned that some customers misunderstood our link specifications, thinking that there is a supporting development board for the specification of a separate camera. Here we declare that we will make this form of link According to the needs of most customers, some customers don’t want to use the factory matching lens, but want to change to other. Therefore, in order to save everyone’s cost, we sell the camera and the development board separately so that everyone can match it at will. If you don’t understand anything, you can contact our customer service staff at any time, thank you
