Additional features of this second-generation (G2) driver include reverse-voltage protection along with basic current sensing and current limiting functionality
Measuring frequency up to 20 000 Hz
which lets you detect if something is interfering with their ability to get to their commanded positions
and shorted-load protection
Pololu High-Power Stepper Motor Driver 36v8 bio-sensor Additional features of this second-generationThe Pololu High Power Stepper Motor Driver 36v8, equipped with the DRV8711 IC, enables control of large bipolar stepper motors with operating voltages from 8V to 50V and continuous currents of up to 8A per phase (11A with sufficient cooling). It offers SPI configurable settings, nine microstep resolutions (full step, 1 2 step, 1 4 step, 1 8 step, 1 16 step, 1 32 step, 1 64 step, 1 128 step, 1 256 step), adaptive current control, and optional STEP DIR
