Teledyne FLIR OV5640 FPC Camera Module

This module is directly compatible with the OpenMV Cam H7 platform, utilizing its dedicated camera interface. It can also be interfaced with other microcontrollers like the ESP32-S3 or STM32 series using parallel DVP or MIPI CSI-2 bridges, provided you manage the clock, sync, and data lines. For Raspberry Pi, an adapter converting the FPC connector to the standard Pi Camera ribbon cable is typically required. Always check the pinout and voltage levels (usually 2.8V or 1.8V I/O) to ensure compatibility with your host board.

Configuration is done via the SCCB (Serial Camera Control Bus) interface, which is functionally similar to I2C. You must write to the sensor's internal registers using a microcontroller to set parameters like resolution, output format (JPEG, RGB565, etc.), frame rate, exposure, and white balance. Libraries for OpenMV, Arduino, or ESP-IDF often provide high-level functions for this. For example, to set JPEG QVGA (320x240), you would send specific register values for windowing and format control. Refer to the OV5640 datasheet for the complete register map and timing sequences.

The OV5640 sensor core typically requires a 1.5V to 1.8V digital core voltage and a 2.6V to 3.0V analog voltage for the phase-locked loop (PLL). The I/O voltage (VDDIO) is commonly 1.8V or 2.8V, which must match your host interface. A typical total current draw during active capture can range from 80mA to 150mA depending on resolution and frame rate. Ensure your host board or a separate regulator can supply these stable, low-noise voltages. Incorrect voltage is a common cause of initialization failure or corrupted image data.
