Smoothieboard - The future of CNC motion control
The smoothie project is also about building great collaborative documentation for both users and for developers that is beginner-oriented and as exhaustive as possible. A lot more than is usual is there already on http://smoothieware.org and more is added all the time.
Technical Specs

96MHz - 120MHz 32-bit ARM Cortex-M3 Core, 64KB RAM, 512KB Flash
Allegro A4982 Bipolar Stepper Drivers
-
up to 24V 2A 16x microstepping, digital current control
-
3 to 5 drivers depending on chosen configuration
Up to 6 FETs
-
3 support up to 24V 5A and 3 support up to 24V 12A to control external devices like hotends, fans and heated beds.
-
3X boards have two small mosfets, 4X have two big and two small, and 5X have 3 big and 3 small.
Lots of room to expand: 4 thermistor ports, 6 endstop ports, SPI, I2C, UART
Robust host options: USB, MicroSD slot, ethernet
Easy reconfiguration!
