USB-C to USB-C cable Arduino is not responding even not powered by this cable

Question

Hi I want to connect arduino NANO to my laptop with Type-C (USB-C) ports (on below image left side [4] and other side 3). Now I bought a USB-C to USB-C cable, because it appeared to be the right tool, but the Arduino is not even powered by this cable. if I use regular USB 3.2 Gen 2 Port (on below image [5]) everythings for fine. but this usb-c ports not recognize the Arduino NANO even NANO's power LED is not switching ON.

On the other hand If I plug in my phone to this usb-c cable it works both ports. It means that cable is working good. I have changed 2 times cable stil not responding.

On the docs, it look usb-c and regular usb 3.2 ports works same. But why usb-c ports not working with Arduino. also my laptop is MSI GS66

I'd appreciate if anyone has a solution or an idea to fix it. Thanks!

• chrisl: Maybe that port does only provide power if you draw enough power from it (like powerbanks often do). When the power LED isn't on but the Arduino works with a USB3 to USB-C cable from another port the problem is not with the Arduino. You can verify the absence of power by measuring the voltage between 5V and ground.
• jsotola: does Arduino Nano have a USB-C connector?
• mehmet: @jsotola urun.n11.com/arduino-urunleri-ve-setleri/…
• chrisl: @jsotola Not the official Nanos, but there are many clones that do have USB-C.
• jsotola: @chrisl just because it has a USB-C connector, it does not mean that it has the circuitry to make it a USB-C interface

Answer 1

That Nano is not USB-C compliant. Yes, it has the connector, but it doesn't do all the required handshaking to put the USB-C port on the laptop into host (and provide power) mode. This is needed because those ports are also power inputs and have to be told to output power - otherwise plug in power to them and bang horrible things happen.

You have to use the larger USB 3.2 ports which are always power providers and never power consumers.

• mehmet: I understood. thanks. you mean if I use usb-c to usb-b converter cable arduino uno should work. or usb-c to mini usb can work original nano.
