An anonymous reader writes: A normal Arduino is easy to use and cheap, but it is a reasonably slow 8-bit processor with limited memory. Why do people use them? They are simple to use and set up. Hackaday shows how to take a cheap ($6) 32-bit CPU in a breadboard-friendly package, plug in a small number of parts (resistors, LEDs, and a cable), and use an online Arduino-like IDE to program it. The chip is way more powerful than an 8-bit Arduino and the code is comparable in complexity to an Arduino sketch that does the same thing. It's an easy way to get into embedded without having to suffer through 8-bit processors. And the new Arduinos also use 32-bit ARM, so that's an option too.
