In einer aktuellen Indiegogo Kampagne präsentiert Elvira Yang mit RUMBA, ein neues “all-in-one” Board für RepRap Drucker.
Das Board mit dem Namen RUMBA (R.eprap U.niversal M.ega B.oard with A.llegro driver) soll als all-in-one Lösung mehrere Funktionen übernehmen uns so Kosten sparen.
Technische Spezifikationen:
* 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 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
– 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)
Das Gerät wird als Open Hardware angeboten, überschritt bereits das geplante Finanzierungs-Ziel um etwa das 5-fache und soll bereits ab 28.Januar verschickt werden. Zur Auswahl stehen unterschiedliche Kits zwischen $59 und $199.
