Take full account of voltage stability, board heat dissipation, practicability and so on, in our research team has been verified. 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.
