Details
The RUMBA (R.eprap U.niversal M.ega B.oard) control board provides a fully integrated all-in-one solution.
Features:
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
- 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
- +5V and +12V
- 2x ADC
- 2x PWM I/O
- 4x I/O
- I2C
Full JTAG support
- JTAG can be used during full operation (no shared pins)
- easy to develop/debug new or optimized firmware using Atmel Studio
