The two versions of the board look very similar
Measuring frequency up to 20 000 Hz
Additional features of this second-generation (G2) driver include reverse-voltage protection along with basic current sensing and current limiting functionality
making it easier to get started using the sensor
EEPROM for data storage: 1024 bytes
Pololu High-Power Stepper Motor Driver 36v8 bio-sensor The two versions of theThe 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
