Camera and LCD modules for stm32h723 mini core development board

[AAlzh.1]

Hi,

I purchased this STM32H723 mini core board that has 20 pin fpc connector for camera module and 10 pin fpc connector for LCD module.

https://www.aliexpress.com/item/1005005852859518.html?spm=a2g0o.order_list.order_list_main.10.d0bd7385STni3J&gatewayAdapt=glo2ara 

I contacted the seller on Aliexpress and they told me this board works with OV2640/OV5640 modules, but they eventually told me that they don't have the items available.

I purchased OV2640, but it turned out to have 24 pin cable.

I have 3 questions:

1. Is there an adapter solution for this ?
2. What camera module will fit this board, please provide Aliexpress product link if possible.
3. What LCD module I can connect to this board ?

Hello,

You need to contact the board's manufacturer as the connectors' pinouts are fixed. Meanwhile this is a list of camera modules that can be used in our boards (from AN5020):

According to the schematics, you need an LCD with SPI or I2C interface but again the connectors' pinouts are fixed. 

Again you need to check with board's manufacturer.

Yep, I think I'll eventually develop my custom SPI/I2C interface to connect LCD with FFC cable.

Hi @AAlzh.1, unrelated to the topic but could you please provide a link to the schematic (documentation in general) of the board? I can not find it anywhere. 

Many thanks for your help!

Hi .. I got it from the seller.

That's the best they could help me with. I'm trying to develop a way to run the camera using adapter board for 20 pins then I hope to find a library for the camera using SPI if things worked as expected.

Several vendors sell the FK723M1-VGT6 boards

Hi @AAlzh.1, likewise, it is a nice board. For me I want to try out Micropython on it.

Many thanks for your help and kindness! Good luck with the project!

Yes, have one here, along with some assorted WeAct boards and cameras (24-pin)

Thanks for the links, actually the board in the link you provided has the exact 24p camera interface for the camera model I have. Where the one I have has 20p.
