USB3.0 Camera Shield Datasheet


Arducam series USB camera shield is a general purpose USB camera control board for PC and embedded signal board computer. It hides the complex nature of the camera and provides the plug and play camera control interface as well as the ready to use SDK library and demo software source code. The Arducam supports variety camera modules from 0.3MP to 21MP or even higher.

Arducam USB3 camera shield is the latest USB3.0 camera shields, it offers the improved performance and enhanced functions than the previous USB2.0 camera shield. It not only supports high resolution and high frame rate image sensors, but also supports stereoscopy camera and IRCUT control feature. With the given camera configuration files, user can switch between different cameras without any effort. It is the ideal solution for camera evaluation/testing, robot/drone, IoT, machine vision and scientific applications.

Pin Definition

Figure 2 shows the connectors of the USB3 camera shield. There are one Micro-USB3.0 connector which can be connected to USB3.0 host controller, and one connector for motorized IR-Cut filter for both daylight and night vision. There are two camera interface on the bottom of the board, one for 8bit camera data bus and the other for 16bit camera data bus. The pin out definition see Table 2 and Table 3.
