3D Printer Controller Board GT2560

1. The firmware is the prevailing Marlin, known for its stability, usability and high performance.
2. Adopt ATmega2560 as the main control chip, together with high-performance USB-serial converter FT232RQ.
3. Power supply: The working voltage is 12V-24V; Dual power supply design supplies power to the heated bed and logic part separately. The current is 12A for the heated bed and 5A for other parts. The cooling fan can support 12V.
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 USB 5V is protected by the USB port with 500mA resettable fuse.
5 ??? 3 x 12V fan outputs and one PWM output for LED or other lighting equipment.
6. 3 x 55A MOSFETs (with LED indicator, the actual output is limited by the PCB board and connector), all 3 MOSFETs are equipped with heat sink to ensure sufficient heat dissipation and stable operation.
