Here are the most important specs:

  • 5 stepper motor drivers (DRV8825)
  • 3 high power MOSFETs for 2 extruders and 1 HPB
  • 3 medium power PWM controlled MOSFETs for up to 3 fans/LED strips
  • 3 analog input ports for thermistors. Noise-filtered inputs and option for shielding
  • 6 inputs for end stops
  • 1 bus for Dallas 1W temperature sensor for monitoring the cold end. Up to 10 sensors can be added to the bus.
  • Microstepping individually programmable for each SMD from 1 to 32.
  • All steppers are controlled by the Programmable Realtime Unit (PRU) for hard real time operation.
  • Single 12 to 24V PSU, fans are still 12V.
  • Compatible with BeagleBone and BeagleBone Black
  • Controllable via Ethernet, USB and Manga Screen
  • Rugged connectors and lots of protection makes it ideal for development.
  • Open source software written in Python for maintainability and hackability.
  • Both hardware, firmware and software are open source under the CC BY-SA licence
