Features: Uses CH340 serial chip to ensure stable and reliable performance, reduce costs, and solve issues with the previous 16U2 hard drive Uses open-source firmware for Marlin, with the same configuration as ramps1.4, and can directly replace ramps1.4 Integrates 2560 and ramps1.4 on a single PCB board, solving the problem of complex setup and easy errors for ramps1.4 assembled interface. Users can adjust their own motor drive Supports A4988/TMC2209/TMC2208/TMC5160/DRV8825 stepper motor drivers 24V input can be accepted, and the same power supply can reduce the hot bed current to 1/4, effectively solving the problem of hot bed MOS transistor heating Can be directly connected to 2004 LCD screen and 12864 LCD screen, supporting TFT28 / TFT32 / TFT35 / TFT50 / TFT70 touch screen Specifications: Product: DIY motherboard MKS GenL V2.1 for 3D printer Material: PCB board Supported motor drivers: A4988/TMC2209/TMC2208/TMC5160/DRV8825 Chipset: CH340 serial chip Uses open-source firmware for Marlin Size: Mixed Power supply support: 24V Note: Due to lighting effects and camera angles, there may be slight color differences between the product in the image and the actual item.
