* Powerful 32 Bit Processor: [http://www.atmel.com/devices/ATSAM4E8E.aspx|Atmel SAM4E8E]: 120MHz ARM Cortex-M4 microcontroller with floating point unit, 512Kb flash memory, 128Kb RAM and many peripherals.
* Dedicated Wifi or Ethernet module: Low level networking is handled by a separate module, this leaves the main processor free to do precise stepper pulse timing and implement other advanced features.

* Super quiet [http://www.trinamic.com/products/integrated-circuits/details/tmc2660-pa/|TMC2660] stepper drivers: SPI controlled and capable of up to 256 microstepping with optional 16x interpolation when using 16x microstepping. Hardware support for variable microstepping and variable stepper current for optimum speed and power efficiency.
* On board High speed SD card and support for a second SD external card if required.
