The RUMBA (R.eprap U.niversal M.ega B.oard) control board provides a fully integrated all-in-one solution. It comes with a set of 5 DRV8825 stepper drivers, which run cooler than A4988 drivers and can handle higher current up to 2A and 1/32 microstepping.


Fully integrated all in one solution

- Arduino 2560-R3 compatible (works with Sprinter, Repetier, Marlin out of the box) (easy to change/flash firmware for end user)
- ATmega16U2 (with enhanced firmware) for high speed USB serial connection (up to 2MBit)


Universal Power

- can be used with 12V-35V for motors / heated bed
- integrated high precision power regulators for 12V (FAN/Light/...) and 5V (ATmega2560/Logic)
- power input selector for ATmega/logic (stand alone or power from USB)


Easy DISPLAY + SD-CARD connector

- RepRapDiscount SmartController compatible pin header on board


Up to 6 motor driver ports with micro stepping

- TRIPLE extruder, or

5x PWM capable power mosfet outputs (3 with voltage selector for MainPower/12V)

- e.g. 3x (MainPower) extruder heater cartridge/power resistor + 1x (12V) fan + 1x (12V) light


1x PWM capable power mosfet with extended cooling area for heated bed

6x end stop connectors with power supply

- Xmin/Xmax/Ymin/Ymax/Zmin/Zmax
- can be used for mechanical, opto, hall, ... end stops


Screw terminals *and* pin header for easy motor connection

- can be used with existing 4 pin Molex plug on motor cable
- easy to attach cables without plug


USB connector and pin header

- pin header is useful when mounting in a small box


Power and ALL unused pins available on EXP-3 feature connector
