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 DUAL Z driver and DUAL extruder, or ....? 5x temperature ADC connectors e.g. 3x extruder thermistor + 1x heated bed thermistor + 1x chamber thermistor 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 Power and ALL unused pins available on EXP-3 feature connector +5V and +12V 2x ADC 2x PWM I/O 4x I/O I2C
