The product can operate bipolar stepping motor in full, half, 1 \/ 4, 1 \/ 8 and 1 \/ 16 step modes. The output drive performance can reach 35 V and ± 2. A4988 includes a fixed turn-off time current regulator, which can work in slow or mixed decay mode. The converter is the key to the easy implementation of A4988. As long as a pulse is input into the \"step\" input, the motor can be driven to generate micro steps. There is no need for phase sequence table, high frequency control line or complex interface programming. The A4988 interface is ideal for complex microprocessor unavailable or overloaded applications.\u003c\/span\u003e \n\u003c\/div\u003e \n\u003cdiv\u003e \n \u003cspan style=\"font-size: 16px;\"\u003e\u003cimg alt=\"12877-A4988步进电机驱动器模块-(3)\" src=\"https:\/\/ae01.alicdn.com\/kf\/Hbbf648daecef46339ac2d769e63bc0a0I.jpg\"\u003e\u003cimg alt=\"12877-A4988步进电机驱动器模块-(1)\" src=\"https:\/\/ae01.alicdn.com\/kf\/H1c9ad4c063714715b7c05b9052c68f53N.jpg\"\u003e\u003c\/span\u003e \n\u003c\/div\u003e \n\u003cdiv\u003e \n \u003cspan style=\"font-size: 16px;\"\u003eA4988 Stepper Motor Driver Module 3D Printer Modular Accessories With Cooling Fin\u003c\/span\u003e \n\u003c\/div\u003e \n\u003cdiv\u003e\n    \n\u003c\/div\u003e \n\u003cdiv\u003e \n \u003cdiv\u003e \n  \u003cspan style=\"font-size: 16px;\"\u003eProduct characteristics\u003c\/span\u003e \n \u003c\/div\u003e \n \u003cdiv\u003e\n     \n \u003c\/div\u003e \n \u003cdiv\u003e \n  \u003cspan style=\"font-size: 16px;\"\u003e1.
