Arduino with Atmega chip have taken hobbyist, students and professionals to a new level where they can easily integrate and can make projects easily. But chip has limitations like less I/O, running at lower 16 MHz frequency, low Ram, no Debugging. These all things can be easily upgraded with ARM Powered Microcontroller like ARM Cortex M3, M4. here are some of the small cheap development boards which can boost up your requirement for extra horse power
1) Teensy USB Development Board.
1) Teensy USB Development Board.
The Teensy is a complete USB-based microcontroller development system, in a very small footprint, capable of implementing many types of projects. All programming is done via the USB port. No special programmer is needed, only a standard "Mini-B" USB cable and a PC or Macintosh with a USB port.
2) Galago
Galago is a tiny revolution in rapid electronics prototyping. It combines a powerful ARM Cortex-M3 microcontroller with a hardware debugger on a tiny circuit board, allowing hobbyists and professionals alike to turn project ideas into reality faster and better than other microcontroller platforms.
