GT2560 3D Printer Controller Board with Power Supply, Compatible with RAMPS 1.4

1. Integrated with the powerful functionality of the RAMPS 1.4 kit, the GT2560 fully replaces it in both software and hardware compatibility, while offering a compact size, more convenient connections, and enhanced stability. 2. Features the ATmega2560 as the main control chip, paired with the high-performance USB-to-serial converter FT232RQ. 3. Power supply: operating voltage range 12V–24V; dual power supply design separately powers the heated bed and logic circuitry. Heated bed current rating: 15A; other components: 10A. 4. Main circuit uses SMD fuse tubes; reverse-polarity protection diode at the power input safeguards the entire circuit. The 5V USB port includes a 500mA resettable fuse. 5. Provides three 12V fan outputs and one PWM output for LED or other lighting devices. 6. Equipped with three 55A MOSFETs (each with LED indicator; actual output limited by PCB and connector ratings); all MOSFETs include heatsinks for effective thermal management and stable operation. 7. Supports up to five A4988 stepper motor drivers (three for X/Y/Z axes, two for extruders); microstepping configuration is set via DIP switches—no jumper caps required for simplified setup. 8. Includes three temperature sensor inputs (100k thermistors recommended). 9. Extended interface supports LCD2004 and LCD12864 displays, plus SD card functionality—enabling standalone printing without a PC. 10. Preloaded with widely used, stable, user-friendly, and high-performance firmware.
