Can i manage this device from windows 10?

[ptt]

Hi 

i have this device

https://es.aliexpress.com/item/1005003425526257.html?spm=a2g0o.order_list.order_list_main.29.21ef194dpi5ufM&gatewayAdapt=glo2esp

Someone can give me some info about how to access it from windows 10?

thanks very much in advance.

Notice:

By default, the STM32 MCU on the module is not open source to customers, and the schematic diagram and PCB of the module are also not open. If the customer wants to program on this MCU by himself for secondary development, he can contact Hot Wheels Negotiate open things (additional fees are required).

thanks for your response. i do not want to develop. i only want to send new qr codes via com port as the seller announces for the product... im lost about this...

The interface looks like TTL serial so yes it can be managed from a PC with a USB to TTL adapter. On that aliexpress page click on VER MAS and it will show the pinout and programming details.  Enjoy :)

That would suggest if you have a USB-to-CMOS Serial adapter to provide power and serial connectivity you could use a Terminal application or your own code to send command/data packets to the display in the manner the vendor documents/describes.

Well, it's time to learn Chinese...

Thanks very much for your responses.

i attached 2 pictures when i show the device has an USB connector. When i connect it, the device starts and seems to work. But i have some questions:
- Why is needed to provide power? is not ok like now?

- The device has no other connector where to connect another one or pins holes...
- When i connect the USB, i do not see COM Port on Windows 10. Windows doesnt recognize the device.

I dont know what to do... :(

once again, thanks very much for your help.

Looking at the image attached, seems the Micro-B USB connector is what i need to use. The question is: any normal USB wire is ok for this?

This connector is not USB. It is TTL serial, with power.

They've chose not to implement USB, but rather use the standard connector as a means to power (say USB charger), and provide serial wiring for an MCU, rather than the D+/D- connectivity for USB.

No one here is highly invested in this part/board, you'll need to analyze the board from a electrical/software standpoint, and it's usability in your desired application. Perhaps there is someone in your team that has a more in-depth understanding of MCU's and interfacing, who might be able to assist or direct you?

Hi again. Finally i solved the situation. I do not use the integrated USB port in the card because i do not have a wire in this moment. 

But i have the wire on the picture attached. Once connected to the board, all is working.

Thanks very much for your support. You put me in the right direction.

BTW, i will now look for the possibility to connect the device to a wifi. any idea?
