Rumba Controller Board RepRap 3D PRINTER

RUMBA (R.eprap U.niversal M.ega B.oard with 

A.llegro driver)

The RUMBA board is a feature rich all-in-one electronics solution for Reprap and other CNC devices. It features an onboard ATmega2560. Its six motor outputs are powered by pin compatible stepper drivers. The board features a developer friendly expansion port supporting giving access to all unused I/O, ADC and I2C pins. The RUMBA board is designed to be flexible in the user's power source availability, allowing any power supply from 12V-35V.
