R.U.M.B.A Features:
RUMBA (R.eprap U.niversal M.ega B.oard with A.llegro driver)
Full Details available here: http://www.reprap.org/wiki/RUMBA
* 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 drivers with easy micro stepping setup (micro switches)
– 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
