This breakout board for STMicro’s STSPIN820 microstepping bipolar stepper motor driver offers microstepping down to 1/256-step and a wide operating range of 7 V to 45 V. It can deliver up to approximately 0.9 A per phase continuously without a heat sink or forced air flow (up to 1.5 A peak). The module has a pinout and interface that are very similar to that of our popular A4988 carriers, so it can be used as a drop-in replacement for those boards in many applications.

  • 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 (for a lower-voltage alternative, consider the STSPIN220 carrier, which operates from 1.8 V to 10 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
  • Motor Driver: STSPIN820
  • Minimum Operating Voltage: 7V
  • Maximum Operating Voltage: 45V
  • Continuous Current Per Phase: 0.9A
  • Maximum Current Per Phase: 1.5A
  • Minimum Logic Voltage: 2V
  • Maximum Logic Voltage: 5.5V
  • Microstep Resolution: Full, 1/2, 1/4, 1/8, 1/16, 1/32, 1/128, 1/256
