What a lot of marketing BS! Their FPGA is not open source and the tools used to program the FPGA aren't either. How is that open and how can they prove anything then about security?

And 16 MB of RAM?

They also fail to mention there exist more powerful FPGA boards for half the price (for instance [URL="https://www.96boards.org/product/ultra96/"]this[/URL]).

That being said I like it :smile:

Nope, not so fast... Low res Mono LCD? When TFT modules with larger resolution cost [URL="https://www.aliexpress.com/wholesale?SearchText=tft+lcd+display&SortType=price_asc"]peanuts[/URL]? (scroll few pages to get to the interesting stuff)

I wonder how (chemically) they get semiconductor action out of plastic. :question:

The original article from ARM offers more insight.

[U]Pre[/U]-order? It means they don't have it yet? And... Freaking power hungry... Not recommended.

(my underline). It means about... what? 20 minutes of full work time?

A 5Ah battery lasts 5h. Hmm, let's see, a tricky calculation of 5Ah/5h = 1A draw in standby. Yuck. :yucky:

Considering the weight of the battery and things, it would be more convenient to have a normal grain-of-sugar-size silicon CPU running at a few milli-amps and a much smaller battery.

Yeah, joking apart, is probably the LED backlight what takes 99% of the juice, and not the ARM cores. If you turn the backlight off it will last much longer. They probably formulated it bad, or the journalist didn't understand. But it is funny, nevertheless.
