Integrated with the mighty function of the Arduino Mega2560+Ultimaker and Arduino Mega2560+ramps 1.4 kit, The GT2560 can not only take full place the them on respect of both software and hardware, but also features compact size, more convenient connection, and more stable.
Adopt ATmega2560 as the main control chip, coupled with the high-performance USB serial converter FT232RQ.
The main circuit adopts SMD fuse tube, the diode added to the power port can provide reverse protection to the whole circuit, in addition, the 5V USB is USB port protected with 500mA Recoverable fuse.
3 55Amp MOSFET (with LED indicator, the actual output is restricted by the PCB board and the connector), all 3 MOSFET are equipped with heat sink to ensure sufficient heat dissipation and stable operation.
Support 5 A4988 stepper drivers (3 for X/Y/Z axis, and 2 for extruders); the subdivision of stepper motor can be setup by dial switch, eliminating jumper caps, easier to operate.
