Wondering where STM found the AS-BC538A3M6-63(1.02.A3265) Camera Module

[Carson]

Hello, 

 

I was wanting to make my own camera board and I wanted to use the same camera that is on STM's Camera board MB1854 and I looked up that manufacturer part number (AS-BC538A3M6-63(1.02.A3265)) and nothing showed up, and when I looked up just AS-BC538A3M6-63 then the only result was STM's example schematic for the MB1854 camera board. I then tried looking up the company they listed on the BOM (HONGJIA) and still found nothing. Does anyone know how to find the board or even some contact info for that company? 

 

Thanks

Hi,

Board could be purchage thru ST or usual distributors: https://www.st.com/en/evaluation-tools/b-cams-imx.html#sample-buy

The AS-BC538A3M6-63 is probably a custom module (sensor + optics) build by HongJia, based on IMX335.

Company could be found here: http://www.topbestcamera.com

If you are building a product, I think many other CSI modules could work with STM32MP25.

Hi @Carson ,

I don't know if @PatrickF could correct me if I'm wrong about any of this?

ST produce general purpose and specialist image sensors and I think the Linux drivers for all of these image sensors are open source and part of the mainline Linux kernel so should work with STM32MP25 MPUs - it may be worth also considering a camera based on one of the ST image sensors - here's the product selector:

Sony also produce a wide range of image sensors and I know that a mainstream Linux driver is available for the 12 Megapixel Sony IMX708 sensor so it should work with STM32MP25 MPUs but I'm not sure about other Sony image sensors.

The newer STM32MP257 MPUs have a built-in MIPI CSI-2 camera interface which was implemented as an external chip in older STM32MP25s.

I'm also looking into using the same camera module from the STM MB1854 board and ran into the exact same issue. Searching for AS-BC538A3M6-63 or the full part number doesn’t yield much beyond ST’s own schematic, and the listed manufacturer, HONGJIA, doesn't seem to have a web presence or any accessible contact info. It’s possible that this is a custom or OEM part made specifically for STMicroelectronics.

If anyone has more information, like a datasheet or supplier contact, or even a known compatible alternative, I’d really appreciate any insight. I'm currently working on a similar camera board project and would love to connect with others going down the same path.

Hi @grayethan426 , @Carson and @PatrickF 

We've been evaluating the new ST VD56G3, VD66GY and VD16GZ image sensors and comparing them with the IMX335 in the MB1854 camera board and other image sensors - optically, our results from the ST image sensors are very good and the ST image sensors also have the strong advantage of having Mainline Linux drivers.

I thought I'd let you know in case this is of help for your application.

ST are currently developing VD5943 and VD1943 image sensors but the timeline for launch doesn't seem to be clear yet.
