Features: 1.Support Drivers: Integration 2560 and for ramps1.4 integrated on a board, solving the problem of complex and easy failure for ramps1.4 composite interface. Users can replace the motor driver, support A4988 TMC2209 TMC2208 TMC516 DRV8825 stepper driver 2.Open Source Firmware: Printer main control board using for Marlin open source firmware, configuration and for ramps1.4 exactly the same, can directly replace for ramps1.4. 3.24V Input: 3D printer main control board can accept 24V input, and the same system power can reduce the hot bed current to 1/4, which effectively solves the hot bed MOS tube heating problem. 4.Connecting Display: Directly connect 2004LCD display and 12864LCD display, which can support TFT28 TFT32 TFT3 TFT50 TFT70 touch screen. 5.Easy to Connect: X Y Z axes use different color terminals corresponding to the motor and limit switch, easy to connect, reduce the probability of plugging down and prevent the driver from backward plugging damage to the motherboard. specification:Item Type: MKS Motherboard Material: 4 Layer PCB Application: 3D Printer Input Voltage:DC12V-DC24V Supported File Format: G Code Support Driver:For TMC2130, for TMC2130SPI, for TMC2208,2209, for TMC2208UART, ST820, for DRV8825, A4988 Applicable For: For LCD2004,for LCD12864,for MKS TFT24 28 32 35 70 PackageList:1 x MKS Motherboard 1 x USB Cable 30 x Jumper Hat Note1. Make sure the positive and negative terminals are properly connected before powering on. 2. Do not plug or unplug the driver while charging, otherwise the driver will be easily burned out. 3. Do not adjust the drive current when the motor is running.
