USB2.0 Camera Shield Rev.E Datasheet

1. Introduction

The highlight of the new USB2.0 camera shield Rev.E is that it supports MIPI interface sensors without any MIPI adapter board. It has onboard 16MByte hardware frame buffer, and overcome the bandwidth and dropping frames issue when using the software frame buffer scheme. In addition, with the onboard frame buffer, it supports synchronized multiple cameras taking images exactly at the same time. Now it well supports both PC and an embedded system like Raspberry Pi, and also can provide customized support for Odroid, Beaglebone Black, Nvidia Jetson TK/TX boards.

5. Pin Definition

Figure 2 shows the connectors of the USB2 camera shield. There are one Micro-USB2.0 connector which can be connected to USB2.0 host controller, and one connector for motorized IR-Cut filter for both daylight and night vision. There are two different camera interface provided on the USB camera shield, but only one camera interface can be used at a time see Table 3 and Table 4.
