 The Arduino clone is just like a regular Arduino but this one has a serial port and the labeling of the ports is more like the real Atmega328 pin mapping. The Arduino clone is just like a regular Arduino but this one has a serial port and the labeling of the ports is more like the real Atmega328 pin mapping.

-The controller board was a bit of a chalange because I tried to design it myself with the two chips that were designed specifically for this: the [[http://​www.st.com/​internet/​com/​TECHNICAL_RESOURCES/​TECHNICAL_LITERATURE/​DATASHEET/​CD00000063.pdf|L297 STEPPER MOTOR CONTROLLERS]] and the [[http://​www.st.com/​internet/​com/​TECHNICAL_RESOURCES/​TECHNICAL_LITERATURE/​DATASHEET/​CD00000240.pdf|L298 Dual Full Bridge Driver]]. This is no simple task if you need to do it on a single layer PCB. So in the end I just bought the simpler L298 driver board so I could get started.+The controller board was a bit of a chalange because I tried to design it myself with the two chips that were designed specifically for this: the [[http://​www.st.com/​internet/​com/​TECHNICAL_RESOURCES/​TECHNICAL_LITERATURE/​DATASHEET/​CD00000063.pdf|L297 STEPPER MOTOR CONTROLLERS]] and the [[http://​www.st.com/​internet/​com/​TECHNICAL_RESOURCES/​TECHNICAL_LITERATURE/​DATASHEET/​CD00000240.pdf|L298 Dual Full Bridge Driver]].
