Geeetech New Rumba ATmega2560
1 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;
2 Five interfaces as input for temperature sensor.
3 All pins being drawn out to permit more function expansion.
4 With expanding interface, it can connect the LCD displayed and the development board.
5 Servo’s expanding interface to make the automatic leveling easier to add
6 Supporting 6 pieces of 16 micro stepping drivers of A4988.
7 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.
8 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.
9 Adopt the popular control board firmware-Marlin, which has good stability, usability and function.
Compiling environment: Arduino IDE
