Description
This breakout makes it easier to use Toshiba's TB67S279FTG microstepping stepper motor driver with adjustable current limiting and seven microstep resolutions (down to 1/32-step). In addition, it dynamically selects an optimal decay mode by monitoring the actual motor current. The module can automatically reduce the drive current below the full amount when the motor is lightly loaded, to minimize power and heat.
The TB67S279FTG has a wide operating voltage range of 10 V to 47 V and can deliver up to 1.2 A per phase continuously without a heat sink or forced airflow (up to 2 A peak). It features built-in protection against undervoltage, overcurrent and overtemperature. It additionally provides reverse-voltage protection (up to 40 V).
