This breakout board makes it easy to use Toshiba’s TB67S249FTG microstepping bipolar stepper motor driver, which features 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, and it can automatically reduce the driving current below the full amount when the motor is lightly loaded to minimize power and heat. The TB67S249FTG has a wide operating voltage range of 10 V to 47 V and can deliver approximately 1.7 A per phase continuously without a heat sink or forced air flow (up to 4.5 A peak). It features built-in protection against under-voltage, over-current, and over-temperature conditions; our carrier board also adds reverse-voltage protection (up to 40 V).
