Supported Drivers: Integrates 2560 and ramps1.4 on a single board, resolving complex issues and errors of the ramps1.4 composite interface. Users can swap motor drivers, supporting A4988, TMC2209, TMC2208, TMC516, and DRV8825 stepper drivers. Open Source Firmware: This 3D printer main control board uses Marlin open-source firmware, with configurations identical to ramps1.4, allowing for direct replacement. 24V Input: The main control board accepts 24V input. The same system current reduces the heated bed current to 1/4, effectively solving the problem of MOS tube overheating in the heated bed. Display Connectivity: Directly connects to 2004LCD and 12864LCD displays, and supports TFT28, TFT32, TFT35, TFT50, and TFT70 touchscreens. Easy Connection: X, Y, and Z axes use different colored terminals corresponding to the motor and limit switch, making connections easy, reducing the chance of incorrect connections, and preventing driver damage from reverse connection.
