This product is a carrier board or breakout board for the STSPIN820 stepper motor driver from STMicroelectronics (ST). 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.

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 (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

The STSPIN820 stepper motor driver carrier ships with one 1×16-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.
