Overview

This product is a carrier board or breakout board for Toshiba’s TB67S128FTG stepper motor driver. we therefore recommend careful reading of the TB67S128FTG datasheet before using this product. This stepper motor driver offers microstep resolutions down to 1/128 of a step, and it lets you control one bipolar stepper motor at up to approximately 2.1 A per phase continuously (5 A peak) without a heat sink or forced air flow. The board breaks out every control pin and output of the TB67S128FTG, making all of the driver’s features available to the user.

Here are some of the board’s key features:

  • Two interface modes to select from:
    • clock mode for simple step and direction control
    • serial mode for controlling the driver’s many features through a serial interface (this mode also allows for serial control of the current limit)
  • Eight different step modes: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, 1/32-step, 1/64-step, and 1/128-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
  • Four different decay modes: mixed decay (two timing ratios), fast decay, or Advanced Dynamic Mixed Decay (ADMD), which 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: 6.5 V to 44 V
  • Can deliver up to approximately 2.1 A per phase continuously (5 A peak) without additional cooling
  • Can interface directly with 3.3 V and 5 V systems
  • 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
  • Carrier board breaks out all of the TB67S128FTG pins in a compact size (1.2″ × 1.6″)
  • Exposed solderable ground pad below the driver IC on the bottom of the PCB
  • Size: 30 x 40 x 8 mm
  • Weight: 5.7g

Included hardware

This product ships with all surface-mount components installed as shown in the product picture. However, soldering is required for assembly of the included through-hole parts. The following through-hole parts are included:

  • Two 1×16-pin breakaway 0.1″ male header strips
  • Three 2-pin, 3.5 mm terminal blocks (for board power and motor outputs)
  • One 0.1″ shorting block (for optionally connecting IOREF to the neighboring VCC pin when using this driver in 5 V systems)

The 0.1″ male headers can be broken or cut into smaller pieces as desired and soldered into the smaller through-holes. These headers are compatible with solderless breadboards, 0.1″ female connectors, and our premium and pre-crimped jumper wires. The terminal blocks can be soldered into the larger holes to allow for convenient temporary connections of unterminated power and motor wires (see our short video on terminal block installation). You can also solder your motor leads and other connections directly to the board for the most compact installation.
