Stepper Motor Driver Board LV8729 for 2 Phase Motors

Features: Support synchronizing, 2, 4, 8, 16, 32, 64, 128, a total of 8 Micro-step modes. The maximum output current is 1.8A, which can be adapted to various 2-phase small stepping motors within 1.8A. The current is 0.3-1.8A Stepless adjustable,and can be set at will. Input working voltage is DC 7-30v. It is equipped with power indicator and working indicator. The input circuit has the power anti-connection reverse design, which is safer to use It has automatic half current on/off function by switch M4, ON is to open half current, OFF is to close half current. Equipped with a large heat sink, and installation of fixed columns, screws, more convenient to use. Specifications: Product name: stepper motor drive board Model: LV8729 Maximum output current: 1.8A Weight:55g Micro-step setting: Micro-step: M1 M2 M3 Synchronizing: ON ON ON 2 Micro-step: OFF ON ON 4 Micro-step: ON OFF ON 8 Micro-step: OFF OFF ON 16 Micro-step: ON ON OFF 32 Micro-step: OFF ON OFF 64 Micro-step: ON OFF OFF 128 Micro-step: OFF OFF OFF Notes: 1. The minimum power capacity of the driver must be more than 2A. Otherwise the work is not stable. 2. The motor wire AB phase wire can't be cross-connected , otherwise the driver will be burnt. 3. When used with PLC, a series of about 2K current limiting resistors should be added, otherwise the driver will be burnt.
