| − | 1.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.
| |
| − | 2. Adopt ATmega2560 as the main control chip, coupled with the high-performance USB serial
| |
| − | converter FT232RQ.
| |
| − | 3. The power pack: operating voltage is 12V-24V; double power supply design feeds for
| |
| − | heatbed and logical part separately. The current is 15A for heatbed and 10A for other parts.
| |
| − | 4. 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.
| |
| − | 5． 3 12v fan output and one PWM output for LED or other lighting equipment.

| |
| − | 6. 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.
| |
| − | 7. 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.
| |
| − | 8. 3 temperature sensor input (100k thermistor is recommended)
| |
| − | 9. Extended LCD and SD card interface support both LCD2004 and LCD 12864, with which
| |
| − | you can print without your PC.
| |
| − | 10. The firmware is the prevalent Marlin, which is known for stability, usability, and
| |
| − | high-performance.
| |
| − | Update log:
| |
| − | 1. A 3-pin straight pin is added to connect with 3D
