Another benefit of using the USB interface is that only one data pair as well as a power and ground connection is needed to interface with the device. This enables plug-and-play operation of external webcams. The UVC specification is short for USB Video Device Class and allows video streaming devices to be used without a hardware specific driver. ![]() Usually, both internal and external webcams are connected via a USB interface that supports the UVC protocol. A few global control lines are needed alongside this interface as well. A standard serial SCCB interface is used to control the sensor. The image data stream is transmitted over a MIPI-CSI2 interface. This sensor provides a high definition 1080p image at 60 frames per second. The image sensor we will be using is an Omnivision OV2740. The webcam, or image sensor interface, is first. We have four logical connections that have to be established with the motherboard: 1. Let's start by figuring out how the webcam/sensor PCB should be interfaced with the mainboard of the system. In this update, we will focus our attention to the electronics and PCB design of the webcam module.įully assembled webcam/sensor PCB Mainboard Interface We’ve decided which PCB technology we would like to use, and what the mounting hardware for the webcam PCB looks like. Welcome back to the open-source laptop project series! In the previous update, we discussed how to integrate the various sensors and the electronics assembly itself into the bezel of the laptop display. ![]()
