This begs the question, what are the best price-quality ratio cameras compatible with this board?

As I understand, both Jetson Nano and Google Edge TPU/Coral Dev Board would work with the same set of cameras, having the MIPI-CSI2 interface. Is it?

Many ML inference applications are using a camera, yet it's close to impossible to find something very affordable.

>> Nor does the TPU dev board. Yes it does require you to send your model to Google: https://coral.withgoogle.com/web-compiler/

And you have to check a box that says "I agree that my model will only be used for applications that follow Google's AI Principles." Wow.

Which may or may not include automatically killing people via drones.

Depends what you want. The cheapest decent machine vision cameras that I know of are Basler's dart range, but they're still $100-300. Entry level is the DA2500-14uc (5MP 14fps).

You can also try places like Leopard Imaging or eCon systems. Even then, most of eCon's stuff is $150+ and their APIs feel a bit hacky.

This is all USB3. Unless you really need a mipi solution (you may need an adaptor board to match the), USB is fine. Even a webcam might be good enough.

I wish these tiny SBCs came with SATA or m.2 so I could hook up an SSD. I know microSD is catching up, but it's not there yet.

On the TX2 they had the Auvidea expansion board that was tiny and where they had an M.2 socket. It did have some stuff not working in the kernel tough so you had to do some changes and rebuild it for it to work. A pain in the butt.

why would you want to train on the device itself?

In some applications you may want to run a continual learning algorithm so it will continually train on new data as well as make inferences.

I always wonder how one would guarantee stability / convergence when learning in the field. Sounds great, but how can this be pulled off in a reliable way? Just dragging down the learning rate does not suffice in my oppinion, as for effective training you should be at the boundary of stability and greedy updates from my experience

the pricepoint is good, relative to the jetson tx1/2 (299-749 usd) and xavier (1099 usd). some of my notes, there is a massive heatsink on this thing, probably for both the a57 cpu and maxwell gpu, this will make your case a bit larger than say the rpi. not sure how the a57 compares to rpi’s a53, i assume both are armv8, quad-core. the inputs seem identical to rpi 3 model b+, hdmi, ethernet, 4 usb (seems 2.0), mini u…

The nano has a single USB3 PHY and 3x USB 2. The dev board may have a hub though. https://www.nvidia.com/en-gb/autonomous-machines/embedded-sy...

Because it's a M.2 E slot, which has no SATA. Maybe there are SSD drives now that can use PCI and fit in the smaller E slots? There didn't used to be. If so, great...

just no SATA? or no SATA and no NVMe?

The development kit specifically lists NVMe as an option

$99 seems like a pretty good deal, am I missing anything? 4 gigs of RAM and _reasonable_ eMMC + PCI expansion could allow it to be a cheap casual use workstation, right? How does it stack up with the RK3399 in the RockPro64? I'm assuming the GPU and software support is better?

From what I read you would have to purchase the $129 board for EMMC support. The $99 board was micro SD only.

Look at this lead pencil. There's not a single person in the world who could make this pencil. [0] [0]: Milton Friedman https://www.youtube.com/watch?v=R5Gppi-O3a8

Sorry to differ, I think this is twisted by an era where liberal market was held as god like status. Take the rubber and metal out because for now. To draw a dark line on a surface, you take the first bit of wood you find, grind it into a point and burn it. You have a pencil. I really believe that the free market centuries made people believe it was the only or most efficient way to get an object done, just like peop…

You’ve moved the goal posts.

It’s not that the construction of some thing, anything, that can be used to write with is difficult. As you point out a piece of charcoal isn’t hard to make.

Milton Friedman’s point is that even something as simple and inexpensive as a pencil involves people all over the world working together to create it. Some mine graphite, some run ships to move the graphite, some manufacture paint, some grow rubber trees, etc. All of this activity, coordinated and made efficient by the market is behind even a simple thing like a pencil.
