A4988 Stepper Motor Drivers with Heatsink For SKR V1.3 1.4 GTR V1.0 MKS GEN V1.4 board

A4988 Stepper Motor Drivers 3D Printers Parts Module with Heatsink For SKR V1.3 1.4 GTR V1.0 MKS GEN V1.4 board A4988 is a complete micro-stepping motor driver with a built-in translator for easy operation. This product is available in full, half, 1/4, 1/8, and 1/16 step modes operates bipolar stepper motors, output drive capacity of up to 35 V and ± 2 A. A4988 includes a fixed off-time current regulator, the regulator in slow or mixed decay modes. A4988 converter is the key to easy implementation. As long as the "step" input inputting one pulse drives the motor one micro step. There are no phase sequence tables, high-frequency control lines, or complex interfaces to program. A4988 interface is very suitable for a complex microprocessor that is unavailable or is overburdened. In the micro-step operation, A4988 chopping control inside automatically selects the current decay mode (Slow or Mixed). In mixed decay mode, the device is initially set to a fixed downtime in some fast decay, the
