Hello, Internet community!

This is my first time posting in a forum, and I need some advice for a project I'm working on. I'm designing two devices that can send and receive files using 5G technology.

In more detail, I'm aiming to design a PCB that includes a processor capable of handling large file transfers (1-5 GB) at high speeds. Display support isn't necessary, but I do need the ability to connect via protocols like SSH. Alongside the processor, I'm planning to use an MT7612U Wi-Fi chip, which will be a key component for both the transmitting and receiving circuits.

After two weeks of extensive research, I feel like I've hit a dead end. I realized I need a better understanding of embedded systems to properly connect the processor to the Wi-Fi chip.

Does anyone have advice on how I can successfully complete this project? Specifically, where should I start, and what type of processor would best support the high-speed capabilities of the MT7612U Wi-Fi chip?

Thank you in advance for any help!

 

I'd use something like a RPi (Linux machine) with a USB adapter for this. Designing a original, new PCB for a controller and the MT7612U Wi-Fi chip is a path were angels fear to cross.

I believe the way you have chosen to meet your design requirements, is complex enough that if you have to ask how to do it, it's not something you should do.

My concerns about the project's success have increased now. Why is this so difficult? Can't I connect the MT7612U chip to the processor used in the PCB design using the UART protocol?

Yes I know it's complicated and difficult but it's not impossible right? If you have any suggestions that could help me get started I would be very grateful.

If you need to ask then it's likely you have no idea why it's so difficult and are unlikely to really understand an explanation of why. No, the chip is designed for USB, not a UART TTL serial protocol.

If you didn't even understand how the MT7612U is connected from the data sheet, then yes, I think it may be impossible for you.

ok thank you i've made a mistake when i said uart it's because i use arduiono all the time. Let me rephrase the question.Can't I connect the MT7612U chip to the processor( with it's componets) used in the PCB design using the USB protocol?
