Arducam Shield Mini 2MP Plus

1. Introduction (#1-introduction)

ArduCAM Shield Mini 2MP Plus is lasted version of mini 2mp camera, it is a high definition 2MP SPI camera,

which reduce the complexity of the camera control interface. It integrates 2MP CMOS image sensor OV2640,

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.

2. Feature (#2-feature)

2MP image sensor OV2640

M12 mount or CS mount lens holder with changeable lens options

IR sensitive with proper lens combination

I2C interface for the sensor configuration

SPI interface for camera commands and data stream

All IO ports are 5V/3.3V tolerant

Support JPEG compression mode, single and multiple shoot mode, one time capture multiple read

operation, burst read operation, low power mode and etc.

Well mated with standard Arduino boards

Provide open source code library for Arduino, STM32, Chipkit, Raspberry Pi, BeagleBone Black

10/15/2020 Print Article 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. 5.

10/15/2020 Print Article The I2C interface is directly connected to the image sensor OV2640. It should be well initialized before normal operation, or else there is no output from the sensor. The OV2640 I2C slave address is 0x60 for write and 0x61 for read. User can use I2C master to read and write all the registers in the OV2640 sensor. For more information about the OV2640 register, please refer the OV2640 datasheet. The Figure 5 shows writing value 0x01 to the OV2640 register 0xFF.
