A USB 2.0 camera module is a small digital camera that can be connected to a computer or other device using a USB 2.0 connection.
1. Composition of USB 2.0 Camera Module
A USB 2.0 camera module typically includes the following components:
Image sensor:
This is the component that captures the image, it is usually a CCD (charge-coupled device) or CMOS (complementary metal-oxide-semiconductor) sensor.
Lens:
This component focuses the light onto the image sensor, it can be fixed or adjustable.
Image Processor:
This component processes the data from the image sensor and converts it into a digital signal that can be transmitted over USB.
USB controller:
This component manages the communication between the camera module and the host computer over the USB connection.
Power Management Unit:
This component manages the power supply to the camera module and can include a battery or a DC/DC converter.
Mechanical housing:
This component protects the internal components of the camera module and can include a mounting mechanism for attaching the camera module to a host device.
PCB:
The Printed Circuit Board (PCB) is where all the components are mounted, it connects all the components and allows them to communicate with each other.
Please note that the specific components and their composition of a USB 2.0 camera module may vary depending on the manufacturer and the intended application.
