Pololu STSPIN820 Stepper Motor Driver Carrier

Item number: 2018935

EAN: 4260513995040

Pololu item #: 2878

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 7V to 45V. It can deliver up to approximately 0.9A per phase continuously without a heat sink or forced air flow (up to 1.5A 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.

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 0.9A 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: 7V to 45V (for a lower-voltage alternative, consider the STSPIN220 carrier, which operates from 1.8V to 10V)
  • Can deliver 0.9A per phase continuously without additional cooling
  • Can interface directly with 3.3V and 5V systems
  • Over-temperature thermal shutdown, over-current shutdown, and short circuit protection
  • 4-layer, 2oz 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
Included hardware

The STSPIN820 stepper motor driver carrier ships with one 116-pin breakaway 0.1? male headers (for a version of this carrier with header pins already installed, see item #2879). The headers can be soldered in for use with solderless breadboards or 0.1? female connectors. You can also solder your motor leads and other connections directly to the board.
