TB67S128FTG Stepper Motor Driver Carrier Spedizione:2-4 Settimane * 1x Four Point MicroThis breakout board makes it easy to use Toshibas TB67S128FTG microstepping bipolar stepper motor driver, which features adjustable current limiting and microstepping down to 1 128 step. In addition, it has the ability to dynamically select an optimal decay mode by monitoring the actual motor current, and it can automatically reduce the driving current below the full amount when the motor is lightly loaded to minimize power consumption and heat
