ArduCAM series camera shield is a universal camera control board for Arduino. It hides the complex nature of the camera and provides the plug and play camera control interface as well as the ready to use software source code library and demo code. User can make it works in minutes without writing a line of code. The ArduCAM supports variety camera modules from 0.3MP to 5MP with different format like RAW, RGB, YUV, JPEG and can be well mated with standard Arduino boards.
ArduCAM Shield V2 and ArduCAM-Mini-5MP-Plus are the second generation of ArduCAM products, they offers the improved performance and enhanced functions than the previous revisions. They not only can capture decent 5MP JPEG images, but also can do 5MP full resolution RAW image capture, which makes it to be the ideal solution for IoT and scientific image processing applications. Even more they can record short movie clips as well.
The ArduCAM is straightforward enough that it can be easily used with an Arduino, however this simple interface means that the ArduCAM is equally easily integrated with other single board computers such as the Raspberry Pi and the Beaglebone black. It isn’t just a camera for the Arduino, it’s a camera that because it can be easily interfaced to an Arduino, can be easily interfaced to any single board computer, either directly, or through an Arduino if needed for a larger system without exposed SPI/I2C busses. In short, the ArduCAM brings a plug and play solution to digital cameras at the hardware level.
The author Robert Chin wrote a book for Home Security System DIY PRO using Android and TI CC3200 SimpleLink using ArduCAM CC3200 UNO DIY WIFI Start Kit. If you want to build home security system by yourself, it is right for you to read about it. And now it is available on Amazon.

ArduCAM now released an ESP8266 based Arduino board for ArduCAM mini camera modules while keeping the same form of factors and pinout as the standard Arduino UNO R3 board. The high light this ESP8266 board is that it well mates with ArduCAM mini 2MP and 5MP camera modules, supports Lithium battery power supply and recharging and with build-in SD card slot. It can be an ideal solution for home security and IoT camera applications.

The author Robert Chin wrote a book for Home Security Systems DIY using Android and Arduino using ArduCAM Mini camera module Arduino and Android. For Arduino and its camera fans, it is right for you to read about it. And now it is available on Amazon
This book shows you how to build your own wireless home security system using an Android cell phone or tablet, an Arduino microcontroller, an infrared motion detector, a Bluetooth adapter, and an optional ArduCAM Mini digital camera. All these items are low cost off the shelf parts that are widely available for purchase. This book shows you how to build your own home intruder alarm system that allows you to detect the motion of an intruder and then call out to an emergency phone number using an Android cell phone or just alert you to the intruder with an Android tablet. In addition, an ArduCAM Mini digital camera can be added so that pictures of the intruder can be taken when the motion detector is tripped. You can also use the book’s ArduCAM Mini camera based security system for continuous surveillance of your property. The image data is stored locally on the Android device and does NOT require payment of storage fees as with some home security company plans. This book will also go into the technical details of the hardware set up as well as the author created Android and Arduino software. With these technical details you will be able to customize and expand these systems to suit your specific needs. (more…)
ArduCAM team now announces to release a new CC3200 UNO board which is full featured development board almost like a combination of CC3200 Launchpad plus CC3200CAMBOOST pack from TI while keeping exactly the same size as Arduino UNO and pin out.
It is based on TI simplelink series CC3200 chip, which gives you an ARM Cortex M4 processor with a built-in WiFi stack and radio. It supports things like web servers and SSL out of the box. It can be mated with existing thousand kinds of Arduino shields without effort. It makes writing firmware for these devices easier, since a lot of the work is already done. The collection of libraries aids in getting prototypes running quickly. You can even debug Energia sketches using TI’s fully featured IDE.
In addition to standard Arduino pin out and Arduino development environment, it also has additional ArduCAM standard camera interface, user can use TI Code Composer Studio (CCS) to develop and debug camera based application.
ArduCAM CC3200 UNO has build in SWD and JTAG debug circuit, you do not need additional debugger tools to do the debugging. It supports TI CCS and Uniflash seamlessly. If you’re looking to connect things to the internet, with the goal of building some sort of “Internet of Things,” this new ArduCAM CC3200 UNO board is your right option. (more…)
ArduCAM Mini is optimized version of ArduCAM shield Rev.C, and is a high definition SPI camera, which reduce the complexity of the camera control interface. It integrates 2MP or 5MP CMOS image sensor OV2640/OV5642, and provides miniature size, as well as the easy to use hardware interface and open source code library. The ArduCAM mini can be used in any platforms like Arduino, Raspberry Pi, Maple, Chipkit, Beaglebone black, as long as they have SPI and I2C interface and can be well mated with standard Arduino boards. ArduCAM mini not only offers the capability to add a camera interface which doesn’t have in some low cost microcontrollers, but also provides the capability to add multiple cameras to a single microcontroller.

The image sensors supports kinds of output formats like Raw RGB Bayer, YUV, JPEG, RGB565, RGB555, RGB444 and etc. In preview mode RGB output is preferred and it can be changed to other format when capture mode. In ArduCAM shield the LCD screen only support RGB565 data format, so when Read more…
User frequently reported that the ArduCAM shield doesn’t work with DUE board, and it is now a known issue. We figured out that in the Due board the default SD library speed is much faster than ArduCAM shield. The current ArduCAM shield SPI timing only supports less than 10Mbps. So Read more…
Where to find the source code ArduCAM shield latest library and examples can be downloaded from download section. Please download the correct library for the the different shield version. For the Rev.B please use the V2.x.x or below, for the Rev.C please use the V3.0.0 or above. What are the Read more…
This section describe the hardware feature and user guide for ArduCAM shield Rev.B. If you use later version ArduCAM shield please read the latest hardware user guide. (more…)
This section describe the ArduCAM shield Rev.C hardware feature and user guide. For information about Rev.B, please refer here.
ArduCAM shield hardware integrates all the necessary components to interface with camera modules. User only need a extra support camera modules and a TF/SD card to start image capture.
The shield provide the following features:
Note: (a) Model ArduCAM-F doesn’t not include a 3.2” LCD screen
ArduCAM shield includes to sets of pin out see Figure 1, they are identical in function. One is Arduino standard, it can be well mate with standard Arduino boards like UNO, MEGA2560, Leonardo and DUE etc. The other one is alternative port which can be connect to any platform like Raspberry Pi. The detail pin out for each see Table 1 and Table 2.
