GT2560 is a compact board that impresses with the powerful technology of the Arduino Mega2560. The GT2560 can not only fully replace the Arduino Mega2560 in terms of software and hardware, but also has other premium features: the optimized interfaces avoid unnecessary problems, the high packing density of the highly integrated components saves more space and is easier to mount on most printers.
5 stepper motors, interchangeable drive modules, powerful ATmega2560 processor with 256k memory, 16MHz operating frequency, powerful USB-to-serial converter FT232RQ, all these make the GT2560 an ideal option for a 3D printer controller. In addition, the GT2560 can operate over 12V and output 90W to a MOSFET, which enables higher torque and rotation rate.
12V/24V 15A and 12/24V 10A power supply.
