[sorry for late entry---I posted this to the wrong board, so copying over now]
I am afraid most discussions here miss the point. Fortunately, many of the new 'IoT' embedded designs are open sourced: for instance, BeagleBone, which is an improved version of RasPi, publishes its design and manufacturing data, and invites imitations. THe problem is scale: Beaglebone costs $50 because of the price breaks on PCB and component cost that result from its volume (multiples of 1e5 units). Some people tried to source small variations of BeagleBone Black, and were quoted cost several times higher.
This is the problem Brazil faces: given their market size, what is the realistic production run size? BBB folks could take a risk and spin up a 100,000 unit production run. A Brazilian version would stand a risk of either assuming conservative production run (5000 units, which still is an investment of nearly half million dollars) and pricing itself out of the market, or going for broke and spinning up a 50,000 run---an investment of several million dollars that could go bad if the market wasn't there.
I agree with all the issues mentioned in this post, and was working with a large chip maker on ways to get industrial-grade computers into the market in Brazil. Its a challenge, but there are CMs there who can build locally.
I've scanned the comments and cannot fathom the fascination with the Raspberry Pi. Its based on a vintage processor that's not even available in industrial temperature grades, and the "B" board didn't even have soldered-down storage for reliability. The old ARM core doesn't support current SW. And the form-factor is the most application-adverse layout for connector positions imaginable. Its one saving grace is HDMI video, but it lacks a normal RGB parallel bus used by low-cost LCDs.
Yes, its a good board for educational purposes, sitting on a desk in a warm dry room. Absolutely.
But if you were going to create something new, you'd have to have a hole in your head to consider using the same processor. Freescale and T.I. have much better processors with current SW support, as do many other manufacturers.
Or is this a "fashion" decision and should be posted on "EF Times" (Electronics Fashion Times) ???

This is my understanding as well.
Licensing for the Boadcom processor in the Raspberry Pi is strict and the Raspberry Pi design is closed so duplication would be difficult and if the duplicate is not a clone, then it is just another non-Raspberry Pi.
On the other hand, the BeagleBone Black design is fully published and open and the processors are available from Texas Instruments without restrictions.
Just look at evidence of India and China over last 30 years. India engaged in a mercantilist, protectionist policies, whereas China was much more open although of course nowhere near free market. Both countries had the advantage of a cheap but able and motivated workforce---and yet China did much better.
"Such policies DO work as evidenced by Brazil's thriving and (I gather) respected car industry."
Brazil's economy - and auto sector - is in fact currently doing poorly. Import taxes on foreign automobiles were raised a couple of years ago to a ridiculous 55%, reducing consumers' spending power and ability to buy quality imported cars. At the same time Brazil is/has been a fast growing developing economy and it is much more likely that the country's progress to this point has been *in spite of* such policies and not because of them.
"But if someone in Brazil wanted to set up an R-Pi assembly line, I think, as I said above, it could turn into a win-win situation."
Maybe. Still, trade in general is a win-win situation overall. On the other hand, import restrictions on products in whole or in part simply favor a few domestic companies or industries at the expense of the overall domestic economy (as well as any trading partners whose goods are being restricted). And setting up a domestic industry to produce products that could be imported at less cost does not make sense economically and is likely to impede overall economic progress, not promote it.
@Rich a bit more detail and discussion please. Such policies DO work as evidenced by Brazil's thriving and (I gather) respected car industry.
Where I would agree with you is that a R-Pi is not the same as a completely assembled car - more like a car part -and it is short sighted to put such a heavy tarrif on it. But if someone in Brazil wanted to set up an R-Pi assembly line, I think, as I said above, it could turn into a win-win situation.
@Prabakhar....I prefer to look at it from changing from a lose-lose situation (R-Pi hardly sell any units to Brazil; Brazil loses out somewhat as a result) to a Win-Win situation (R-Pi get royalties rather than sales, and Brazil deveops their industry and gets jobs and expertise development).
Sure, Mr R-Pi must make sure that his product is of good quality when made in Brazil, and Barzil must be scrupulous about sticking to the terms of the agreement. But, as above, VW have done it and they, and Brazil, have done very nicely thank-you.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
