This is way overpriced for what you get if you want to run Linux CNC on if.
This statement is precisely what I have problems with. That's why
clueless people and MS emphasize all the time, how can free software
make you any money. I have no problem paying $300 for a computer that
will run a CNC machine for years to come.
The way you put it can be interpreted that $30 would be too much for you
to pay.
You are paying for the 120 CUDA core GPU which I don't think can be used
for graphics. The GPU is intended for computation, either for vision
processing or machine learning
Computation is computation, like math is a math. Some chips are more
suitable for certain functions than others. If a board is designed to be
used in robot systems including motor control, read all kinds of sensors
including visual spectrum camera, then it's suitable for CNC also. Some
CNC systems work with an arm like mechanism used for welding for
example, where capability to detect things similar to human vision would
be a bonus. Co-robot, co-CNC machines,... meaning they work with humans
without a danger to injure them.
If what you are looking for is a faster BBB, then the Pine64 is that. Or
I described my gripes about poor mechanical design on these boards long
time ago. Cables all over the boards or their sides, inappropriate
connectors in respect to current, vibration, thermal properties is just
bad design.
if you are OK with spending $100 on the Jetson then why not spend $100 on
an Intel Celeron based board?
You mean PC motherboard, unsuitable computer design for CNC from the get go?
It's a good product but this is not its intended use.
PCs were NEVER intended to be used for CNC yet some of you out there use
it for that purpose. I don't blame you. In my research for CNC hardware
I'm still not clear which motherboard to use for CNC because you need to
run a special test to ensure proper behavior with RT kernel which cannot
be done before you buy it.
Jetson-nano board designed for use in robotics and other real time
systems is sure more suitable than RaspberryPi, Baegle board and such
that were designed for toys/education, not industrial use.
The board is not even out yet but definitely worth looking into it IMO.
Don't worry about the single source, drivers or any of that. This is a
standard ARM board that runs Ubuntu Linux and will run just about anything
that can run on Ubuntu Linux but the part that makes this unique is the low
price of the Nvidia GPU.
You are missing the point, overall PCB design with edge connector that
together with a decent backplane could be used the same way as PDP
computers from Digital were used in industrial environments. Boards with
edge connector was in the bottom plugged into Unibus backplane, most
cables from interfaces were in the back with few on the top, all
enclosed in well ventilated box.

Some people have vision, some do not, and some simply follow what a self
