RUMBA board

RUMBA là phần cứng tích hợp mạnh mẽ, giải pháp điện tử trọn gói cho máy in 3D và máy CNC khác. RUMBA cho phép điều khiển một lúc 7 động cơ, bạn có thể tích hợp 3 đầu phun độc lập vào cùng một chiếc máy in 3D.

Lưu ý: Mạch RUMBA chưa bao gồm Stepper driver A4988 hoặc Drv8825, bạn cần mua thêm.

RUMBA hoạt động ổn định, mạnh mẽ, hiệu suất cao hơn RAMPS.

• 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 (DC/DC) 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) which can be used for:
• TRIPLE extruder
• DUAL Z driver and DUAL extruder
• 5x temperature ADC connectors for thermistors:
• 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 USB pin header (useful when mounting in a small box)
• Power and ALL unused pins available on EXP-3 feature connector:
• +5V and +12V
• 2x ADC
