STSPIN220 Low-Voltage Stepper Motor Driver Carrier
This product is a carrier board or breakout board for the STSPIN220 low-voltage stepper motor driver from STMicroelectronics (ST); we therefore recommend careful reading of the STSPIN220 datasheet (1MB 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 1.1A 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
- 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: 1.8V to 10V (for a higher-voltage alternative, consider the STSPIN820 carrier, which operates from 7V to 45V)
- Can deliver 1.1A 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
This product ships with all surface-mount components—including the STSPIN220 driver IC—installed as shown in the product picture.
