STSPIN220 Low-Voltage Stepper Motor Driver Carrier

STSPIN220 Low-Voltage Stepper Motor Driver Carrier


This breakout board for STMicro’s STSPIN220 low-voltage microstepping bipolar stepper motor driver offers microstepping down to 1/256-step and operates from 1.8 V to 10 V, allowing stepper motors to be powered with voltages that are too low for other drivers. It can deliver up to approximately 1.1 A per phase continuously without a heat sink or forced air flow (up to 1.3 A peak).

This product is a carrier board or breakout board for the STSPIN220 low-voltage 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 1.1 A per phase continuously without a heat sink or forced air flow.

Key features:

  • Simple step and direction control interface
  • Nine different step resolutions down to 256 microsteps: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, 1/32-step, 1/64-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: 1.8 V to 10 V (for a higher-voltage alternative, consider the STSPIN820 carrier, which operates from 7 V to 45 V)
  • Can deliver 1.1 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 STSPIN220 low-voltage 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 #2877). 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.
