Rumba 3D Printer Controller Board
Rumba, not the dance more like the controller that will make you start dancing. Based on the ATmega’s AVR processor, Rumba is the core of a 3D printer, carver, laser cutter and other CNC. The integrated design makes it easy to install and debug. Compared with other 3D Printer control board. The headers make this product upgradeable, you can run the A4988 or switch for the DRV8825s for optimal performance! This board has an additional motor port for those who want to try tri color print. This board makes it really worth the value in terms of upgrade features and can operate at 12VDC to 35VDC!
Specifications:
- Use the same CPU as that of Arduino MEGA as main control chip, Atmega2560 cooperates with high-performance USB chip in order that it is compatible with all RAMPS relevant firmware;
- Five interfaces as input for temperature sensor.
- All pins being drawn out to permit more function expansion.
- Extended LCD shield interfaces, supports offline printing( note, SD card slot is not on rumba but on the LCD shield)
- Servo’s expanding interface to make the automatic leveling easier to add
- Supporting 6 pieces of 16 micro stepping drivers of A4988.
- PWM DC output( heating pipe ,fan), six channels of output( 1 channel of high current, 3 channels of medium current and 2 channels of low current). Use low on-resistance MOS Varactor as driver and LED tests each output.
- Power-supply: power input 12v-35v, dual power to avoid interaction; hot bed connects 11A, 12V, other sections connect 5A, 12V and add a 12V cooler to reduce the high temperature from the high current of Mega controller.
- Adopt the popular control board firmware-Marlin, which has good stability, usability and function.
- Dimension:130x70x10mm
