This breakout board makes it easy to use Toshiba’s TB67S279FTG 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 TB67S279FTG has a wide operating voltage range of 10 V to 47 V and can deliver approximately 1.2 A per phase continuously without a heat sink or forced air flow (up to 2 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).

Here are some of the board’s key features:

Simple step and direction control interface
Seven different step modes: full-step, non-circular half-step, circular half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
Advanced Dynamic Mixed Decay (ADMD) dynamically switches between slow and fast decay modes by monitoring the state of current decay (not according to fixed timing)
Configurable Active Gain Control (AGC) automatically reduces drive current to minimize power consumption and heat generation when maximum torque is not needed
Motor supply voltage: 10 V to 47 V
Maximum continuous current per phase without additional cooling:
- TB67S249FTG: 1.7 A (4.5 A peak)
- TB67S279FTG: 1.2 A (2 A peak)
Built-in regulator (no external logic voltage supply needed)
Can interface directly with 3.3 V and 5 V systems
Under-voltage lockout and protection against over-current/short-circuit and over-temperature
Open-load detection
Active-low error outputs indicate over-current, over-temperature, or open-load condition
Carrier board adds reverse-voltage protection up to 40 V
Compact size (1.0? x 1.4?)
Exposed solderable ground pad below the driver IC on the bottom of the PCB

This version uses a TB67S279FTG driver and can deliver approximately 1.2 Aper phase continuously without a heat sink or forced air flow (up to 2 A peak). It can be distinguished by the marking “S279FTG” on the driver IC.
