Stepper Driver 1.5A - Pololu Original

This product is a carrier board or breakout board for the STSPIN820 stepper motor driver from STMicroelectronics (ST); we therefore recommend careful reading of the STSPIN820 datasheet (594k pdf) before using this product. This stepper motor driver offers microstep resolutions down to 1/256 of a step, and it lets you control one bipolar stepper motor at up to approximately 0.9 A per phase continuously without a heat sink or forced air flow (see the Power dissipation considerations section below for more information). Here are some of the driver’s key features:

  • Simple step and direction control interface
  • Eight different step resolutions down to 256 microsteps: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, 1/32-step, 1/128-step, and 1/256-step
  • Adjustable current control lets you set the maximum current output, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
  • Motor supply voltage: 7 V to 45 V
  • Can deliver 0.9 A per phase continuously without additional cooling
  • Can interface directly with 3.3 V and 5 V systems
  • Over-temperature thermal shutdown, over-current shutdown, and short circuit protection
  • 4-layer, 2 oz copper PCB for improved heat dissipation
  • Exposed solderable ground pad below the driver IC on the bottom of the PCB
  • Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects

This product ships with all surface-mount components—including the STSPIN820 driver IC
