3D Printer Part Large Stepper Motor Driver 57 Steps+ Heat Sink Can Drive 57 Stepper Motor for 3D Printer

Descriptions: It has adopted four layers of thick copper PCB and automatic patch processing. The module uses indexer (DIR / STEP) control interface, which provides up to 4A drive current and can drive 57 stepper motor and is compatible with Pololu pin definitions. Features: Four layers of thick copper PCB Allow full step, half step, one quarter step, 1/8 step, 1/16 step, 1/32 step Maximum input voltage: 50V; Maximum output current: 4A (good heat dissipation is required) Equipped with large heat sink, the module can get better cooling effect High efficiency motor current control (advanced dynamic mixing attenuation ADMD, ADMD technology than the traditional hybrid attenuation mode more closely track the input current, in order to achieve high speed conditions, high efficiency motor control) Built-in error detection circuit chip(thermal shutdown (TSD), over-current shutdown (ISD), and power-on reset (POR)) Maximum current regulation: Current limit can be adjusted by measuring VREF and adjust the adjustable resistor; Connect the + to VREF and - to GND and read the value; Specifications: Model: S109 drive Type: driver Maximum input voltage: 50V Maximum output current: 4A 1 x Stepper Motor Driver 1 x Heat Sink '
