ArduCam-Mini OV5642 5MPx 2592x1944px 120fps SPI - camera module for Arduino UNO Mega2560, Raspberry Pi Pico

Description

Camera module for Arduino 5 MPx with a resolution of 2592 px x 1944 and speeds up to 120 frames per second. It extends the capabilities of the system, for example, microcontrollers Arduino, STM32 and mini-computers Raspberry Pi, with the possibility of taking photos and recording video clips. The device operates with a voltage of 3.3 V and 5 V, it communicates via SPI, the angle of view - 24 ° (non-linear), the lens is 1/4".

Modes of operation

• Single Capture Mode - the default mode of the device after the indicating the command via SPI, the camera captures a frame and adds it to the buffer, while setting a flag in the registry. By checking the state of the flag, the user knows that the read has been completed.
• Multiple Capture Mode - an advanced mode where the user specifies the number of frames to be captured. Please note that the number of frames cannot exceed the capacity of the buffer.
• JPEG Compression - in this mode, the output are compressed data in the JPG format with higher resolution, than RGB.
• Normal Read and Burst Read Operation - in this mode, it is sufficient to send a read command for receiving the continuous transmission of frames via an SPI interface.
• Rewind the Read Operation - it allows to read, several times, the same data contained in the buffer.
• Low Power Mode - disables the sensor and transducer in order to save energy.
• Image Sensor Control - mode change parameters of the camera sensor, i.a. balance, brightness, contrast and saturation.

The product is compatible with Arduino

A user manual and library for Arduino are available in GitHub.

Block diagram

The device consists of a lens, sensor and electronic components with the data buffer and the controller of the SPI bus. The user has also access directly to the sensor via the I2C bus.
