1Introduction
ArduCAM-M-5MP is optimized version ofArduCAM shield Rev.C, and is a high definition
5MP SPI camera, which reduce the complexity of the camera control interface. It integrates 5MP
CMOS image sensor OV5642, and provides miniature size, as well as the easy to use hardware
interface and open source code library. TheArduCAM 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.

Active array size: 2592x1944
Shutter: rolling shutter
Lens: 1/4 inch
SPI speed: Max 8MHz Resolution support:
Frame buffer: 512KB 5MP, 1080p, 720p, VGA, QVGA
Size: 34 x 24 mm Format support: RAW, YUV, RGB, JPEG

Note：OV5642 sensor consumes too much current when working in full power, onboard LDOs can
be very hot due to the high voltage drop. Recommend to enter low power mode after capture, or
use lower input power voltage.

6Block Diagram
Figure 2 shows the block diagram of ArduCAM mini shield which is composed by lens,
image sensor and an ArduChip. The lens is changeable and can be mounted by S-mount (M12x0.5)
or CS-mount lens holder. The image sensor is 5MP CMOS OV5642 from Omnivision. The
ArduChip uses ArduCAM proprietary third generation camera controller technology which
handles the complex camera, memory and user interface hardware timing and provides a user
friendly SPI interface.

7Functions
7.1 Single Capture Mode
Single capture mode is the default capture mode of the camera. After issuing a capture
command via SPI port, the ArduCAM will wait for a new frame and buffer the one entire image
data to the frame buffer, and then assert the completion flag bit in the register. User only needs to
poll the flag bit from the register to check out if the capture is done.
7.2 Multiple Capture Mode
Multiple capture mode is advanced capture mode. By setting the number of frames in the
capture register, the ArduCAM will capture consequent frames after issuing capture command.
Note that number of frames should be set properly and make sure do not exceed the maximum
memory space.
7.3 JPEG Compression
The JPEG compression function is implemented in the image sensor. With proper register
settings to the sensor, user can get different resolution with JPEG image stream output. It is
recommended to use JPEG output to get higher resolution than RGB mode, due to the limitation
of frame buffer.
7.4 Normal Read and Burst Read Operation
Normal read operation reads each image data by sending a read command in one SPI read
operation cycle. While burst read operation only need to send a read command then read multiple
image data in one SPI read operation cycle. It is recommended to use burst read operation to get
better throughput performance.

7.5 Rewind Read Operation
Sometimes user wants to read the same frame of image data multiple times for processing,
the rewind read operation is designed for this purpose. By resetting the read pointer to the
beginning of the image data, user can read the same image data from the start point again.
7.6 Low Power Mode
Some battery power device need save power when in the idle status, the ArduCAM offers the
low power mode to reduce power consumption, by shutdown the sensor and memory circuits.
7.7 Image Sensor Control
Image sensor control function is implemented in the image sensor. By setting proper set of
register settings, user can control the exposure, white balance, brightness, contrast, color
saturation and etc.
