Description:KEB3.0 controller board is specifically designed and developed according to the problems of the 3D printer KFB2.0 controller board. The design of the circuit takes full account of the protective facilities, and the double self-recovery fuse prevents the circuit from short-circuit burning out of the device. The 5 channels of high current resistant diodes to prevent reverse connection, even if the power supply is positive and negative, it will not burn the controller board. The pin is designed to be compatible with BaseV1.0 and MKS GenV1.4 controller board, Marlin, Repefier and other open-source firmware which can be downloaded from its website directly.KFB3.0 controller board characteristics:(1) Power step-down voltage chip adopted L5970D chip: work up to 1A outputcurrent, input voltage of 4.4V to 36V, low operation. 100% duty, internal fixedfrequency, 250 kHz voltage feedforward, run zero load current, the zero currentconsumption, shut off the heat, high efficiency, good stability, not easy tooverheating, short circuit protection function, sufficient margin Arduino step-downchip maximum support only 12V, so has been loaded with work is easy to burn out.(2) The USB serial chip adopts CH340T chip, the maximum 2Mbps, thecommunication is stable and not lost, which solves the problem that the compactversion of Windows drive cannot be installed, and supports the whole series ofWindows, Mac, and Linux are operating system. (3) The processor uses the tamega2560 chip, and the 54 output meets the variousoutput interface. (4) Heatbed MOS tube adopts F8736 chip, the largest 18A current, no heating and ulfimaker, the same solution using the Wj500V type wiring terminal, which is larger, easier to connect and durable. (5) Tantalum capacitor filter collection temperature, anti-interference, moreaccurate.Features:Power input: 12V ~ 24VSupport motor drive number: 5Support motor drive type:A4988, DRV8825, LV8729, MS4998,MS4989, TMC2100, TMC2208, TMC2130 and so onSupport control panel: LCD2004, LCD12864, LCD1602, touch color screenCompile environment: Arduino IDE Firmware: MarlinScrew hole size: 4 x 3.3mmSize: 100mm x 100mm
Note:1 Do not power on the motherboard wiring or replacement of each module except for (SD, USB)2. Please note that the positive and negative wiring3. Before the power, please check to determine the connection interface is correct, so as not to damage the motherboard4. Do not touch the motherboard with wet hands5. When an emergency occurs, please press the RESET reset button on the motherboard or disconnect the power
