When you hear the name “Arduino,” does a picture of the Uno come to mind? While the most popular, this 8-bit based board isn’t the only Arduino available today. There are some other boards available like the Due and recently introduced Zero, which are far more advanced than the humble Uno.
These are 32-bit microcontroller boards that have a very different architecture compared to the relatively straightforward Uno. In fact, one of the most striking differences is that the Due and Zero have two USB ports.
What is the difference between the Programming and Native ports on these more powerful Arduino boards?
The lead hardware designer of both the original ARM core and the BBC Micro Computer, Professor Steve Furber, is leading an effort to simulate the human brain with ARM cores. Custom chips with 18 cores each will be used. Check out the story at Electronics Weekly for more information: One million ARM cores to simulate brain at Manche`ster – 7/8/2011 – Electronics Weekly.
Coming Q3 of 2011, ST-Micro will begin selling a Single-Chip GPS IC called the Teseo II. It has an ARM core integrated into it, which should help reduce the time it takes to get a fix, and simplify integration into any hardware project. Pricing is set at $6 in volumes of 500k, so for hobby work it may be a cost/time trade-off. ST selling single-chip GPS IC. – 1/27/2011 – Electronics Weekly.
