Geeetech GT2560 3D Printer Mainboard Controller Board Compatible Mega2560

Highlights

Integrated with the mighty function of the Mega2560 + Ultimaker and the Mega2560+ramps 1.4 kit, GT2560 can not only take full place them on respect of both software and hardware, but also features compact size, more convenient connection, and more stability.

Adopt ATmega2560 as the main control chip, coupled with the high-performance USB serial converter FT232RQ.

The power pack: operating voltage is 12V-24V, double power supply design feeds for heatbed and logical part separately. The current is 12A for heatbed and 5A for other parts. The cooling fan can support 12V

The main circuit adopts an SMD fuse tube, the diode added to the power port can provide reverse protection to the whole circuit, in addition, the 5V USB is a USB port protected with a 500mA Recoverable fuse.

Three 12v fan output and one PWM output for LED or other lighting equipment.

Three 55Amp MOSFETs (with LED indicator, the actual output is restricted by the PCB board and the connector), all 3 MOSFETs are equipped with a 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 set up by dial switch, eliminating jumper caps, easier to operate.

Three temperature sensor inputs (100k thermistor is recommended)

Extended LCD and SD card interfaces support both LCD2004 and LCD 12864, with which you can print without your PC.

The firmware is the prevalent Marlin, which is known for its stability, usability, and high performance.
