I guess that's true, but many projects I see use USB power banks for arduinos and I don't think this is too different.

The 4GB Jetson will run off a micro-usb port (for power banks) OR the barrel adapter.

I run the barrel adapter off a power bank just fine

I have a Jetson nano. It's a nice thing for what it is, and the price. But, the software misses the mark by a lot. It's still based on Ubuntu 18.04. Want python later than 3.6? Not in the box. A lot of python modules need compiling, and the cpu is what you'd expect. Good for what it is, bad for compiling large numbers or packages. They run a fancy modern desktop based on the Ubuntu one. Sure, it's Nvidia, gotta be fl…

Just curious, any guess why it doesn't come with the latest Ubuntu and Python pre-installed?

It’s very easy to install any version of Python using pyenv. I would be careful not to change the system Python in 16.04 because it will probably mess up apt.

What are the use-cases for a GPU-accelerated single board computer?

Apparently there's a big Software Defined Radio (SDR) community that appreciates the TFlops of floating point compute. cuSignal in particular. Note that embedded radios / modems / codec manipulation is incredibly common. Usually its handled by a DSP (VLIW architecture), but I'd imagine that the GPU architecture has more FLOPs. DSPs probably have less latency, but something like SDR is not very latency sensitive (or m…

It looks like at least one company has started to produce products that tie together the radio FPGA GPU compute pipeline for SDR using cuSignal and these Jetson modules: https://www.crowdsupply.com/deepwave-digital/air-t

It's pretty neat stuff to think about DSP on hundreds of MHz of bandwidth being something that you can do in software these days. I remember when that was firmly in the realm of "don't bother unless you want to design a custom ASIC" and now it's starting to become even hobbyist-accessible.

I want to setup something like this for my daughter's primary grade school meetings using Zoom. Any suggestions? Are the Pis or this device up to par now for such use case? I totally do not like Chromebooks, and standard laptops are an overkill.

If you are looking for something that you can use so your daughter can run a browser and then zoom into a class session then I would suggest a Raspberry PI 4GB or 8GB. I have a 4GB Nano. Comparing the Pi 4GB and Nano 2GB. The 4GB of the Pi is an important factor vs the 2GB. Personally I would recommend the 8GB Pi.

There are many more Pi's out there so the development community and support is stronger than Nano. The Nano has support, just not in the same area. I have had problems with the Nano where memory gets chewed up in some way and I just reboot it after a while. The Nano does have the advantage of an Nvidia GPU, but it appears that is of no benefit to you.

Although the Nano does not have built-in wifi I don't think that is a substantial issue, but it does mean you need to get a wifi dongle. Of more concern is the need for a fan on the Nano. I have found that it gets hot fairly easily when pushed.

Bottom line is that in my opinion the small amount of memory is a substantial to avoid the Nano 2GB, the 4GB Pi is good and for about $30 more the 8GB Pi is a definite step up.

NVidia don't see the point. There are a few forum threads where NV respond "why do you even want that" or "you can get ubuntu 20.xx from a third party".

Then why pre-install anything? I'm not in the field, but I would think that a lot of people would want to run there Python CV code on it. Or is it, becaue they want you to use CUDA?

Slightly off topic but I’m wondering if there is a new Nvidia Shield coming out, they seem to have released them end of October in past years...

shield new version are released every 2 years 2015,2017 the latest 2019 so unlikely a new version comes out this year. I still am using the 2015 version as 2019 is not much of an upgrade.

Because if you don't have an offering that'll make it do something interesting OOB, it's unlikely anyone would buy it. [bootstrapping from true scratch is typically a nightmare for hobbyists]

I shouldn't be quite so negative; NV did put in a lot of effort building up the development kit. ARM Builds of CUDA, drivers, etc. Repos with packages for the job. Tutorials for common tasks, etc. They're really within a hair's breadth of an excellent OOB experience, but fell at the last hurdle.

18.04 was the last Ubuntu LTS before very recently, and python3.6 is system python3 for Ubuntu 18.04. These are both Ubuntu examples that Nvidia just left as the default. When 20.04 comes python will upgrade with it.
