100% brand new and high quality Features: MEGA2560 and Ramps 1.4 are integrated in the motherboard, avoiding complicated connectors. Support various step-by-step drives, such as A4988, DRV8825, TMC2100 and LV8729, which can be used to replace stepper drives and motors as users. The external backup controller signal can be used to connect the external high current controller to drive stepper motors 57 and 86. Using high-quality MOSFET, the heat dissipation effect is better and more stable. Use a specific power chip to support 12V-24V power input to solve the problem of chip heating and insufficient power. The stable and reliable filter circuit can greatly reduce the interference and prevent it from falling during the printing process. Use CH340 serial chip, easier to install than 16U2. Run Marlin firmware, the configuration is completely equal to Ramps 1.4, it can directly replace Ramps 1.4. Support Ramps 1.4, 2004LCD, 12864LCD, TFT28 and TFT32. It can be used for 24 V input, the heating bed current can be reduced to 1/4, and the system power is the same, which can effectively solve the heating problem of the heating bed rifle. X-axis, Y-axis and Z-axis use different color terminals to control the stepping motor and the end, which is convenient for cables. Step by step into the driver according to the different colors of the terminal to reduce the possibility of reversing and avoid the controller from damaging the board.
