Power supply for NC

Nano Cortex
21

Janiodin, I hope you’re well!

Although it’s hard to say exactly what’s going on, from how you’ve described the issue I think your culprit may be your USB cable. I’d point you to the user manual at this point, which says “to ensure optimal performance and safety, please use a USB-C power source that complies with the following specifications: 5V - 1.5A”

In your description of the issue, the cable that you provided a link for is a USB 2.0 cable. USB 2.0 generally carries 5V and 500mA. This is suboptimal for NC functionality. Meeting the power demands of the unit isn’t just for optimal performance as the manual states, it’s a safety piece for both yourself and the device. Underpowering any device can lead to damage of said device, and while I can’t comment on what is happening when you unplug/plug in the cable that would cause the Nano Cortex to then power up, I can at least strongly suggest the following: I recommend you use an appropriate USB-C cable to handle the power transmission. I personally use a Thunderbolt 4 cable, which can provide up to 20V and 5A, so I am well covered by the requirements outlined in the manual.

I hope this helps, and for any other readers out there: remember that not all USB-C cables are created equal. Best of luck to you Janiodin :slight_smile:

Hi

Thanks for reply.

I did some further testing and reading.

It seems that USB-C is not just a simple cable. There are all kinds of technical stuff here. But the solution was maybe very simple. I just turned the cable 180 degrees and now it seems to work. Fingers crossed.

My guess is that the usb-c switch cable manufacturer has been little lazy and made the cable not totally symmetrical. So you can plug it wrong way in.

If this is what works for you, then so be it. But I can’t recommend enough the importance of getting the appropriate cable to power your unit. In my case, my thunderbolt cable was $50, which was ~5% the cost of the Cortex… and I’m sure you can find something more inexpensive. It’s a small price to pay to make sure your unit doesn’t just work now but for years to come.

I’m not telling you what to do by any means. Simply put, I’m certainly always going to drive the point home to follow the manual’s instructions for properly powering the unit. Best of luck to you :slight_smile:
