Recommended ≥120° parallel or SPI camera for NUCLEO-H7S3L8

[Srishti]

Hello,

I am looking for a camera module for the NUCLEO-H7S3L8 board, using the STM32H7S3L8 MCU.

My project requirements are:

• Field of view: at least 120° horizontal FOV

• Preferably RGB or YCbCr output

• I would prefer a module that is reasonably easy to connect, with a breakout board or pin header

• I would like to avoid MIPI CSI-2 cameras because the NUCLEO-H7S3L8 does not have a CSI-2 camera receiver or a 22-pin camera connector

The STM32H7S3L8 datasheet, Section 3.26, states that its DCMIPP supports an 8- to 16-bit parallel camera interface, including RGB565, YCbCr 4:2:2 and compressed data such as JPEG. However, the NUCLEO-H7S3L8 board does not appear to have a dedicated camera FPC connector.

I found an ST Community table listing OV2640, OV5640 and OV5642 as examples of sensors supported by STM32 DCMI. I am therefore considering an OV5640 module with a 120° lens, such as this module:

I also considered an Arducam Mega SPI camera because it requires fewer connections, but I have not found a retail version with a documented ≥120° horizontal FOV.

Could you please clarify:

1. Does ST recommend a particular camera module or evaluation board for the NUCLEO-H7S3L8 DCMIPP?

2. Is an OV5640 DVP camera electrically and functionally suitable for the STM32H7S3L8 DCMIPP?

3. Is there an existing STM32CubeH7RS example, BSP driver or reference project for OV5640/OV5642 with DCMIPP?

4. Are all required 8-bit DCMIPP signals available on the NUCLEO-H7S3L8 Morpho or Zio connectors without conflicts with the onboard Ethernet, external flash or other board functions?

5. Can you recommend an easier SPI camera solution with an officially documented horizontal FOV of 120° or greater?

6. Is a custom adapter board required, or is there an existing FPC-to-Nucleo camera adapter?

I am specifically using the NUCLEO-H7S3L8, not the STM32H747I-DISCO or NUCLEO-N657X0-Q.

Thank you.

Hello ​@Srishti and welcome to the community,

 

First of all, I apologize for my late reply.

You need to chose any camera module supports the following components:

• Lens: Focuses light onto the sensor

• Bayer matrix and filter: Used to capture color information by filtering the incoming light into red, green, and blue components

• Optionally, an image signal processor (ISP): Processes images, converting the raw data from the sensor into a usable format

• Data interface such as CSI-2 interface or parallel interface

To find the suitable pins you can use STM32CubeMX 

 Yes, OV5640 sensor is suitable for the STM32H7S3L8.

You can refer to these examples STM32CubeH7RS/Projects/STM32H7S78-DK/Examples/DCMIPP at main · STMicroelectronics/STM32CubeH7RS · GitHub

I recommend you to check the pins conflicts with Ethernet and external flash using STM32CubeMX tool.

 

Thank you.
