Pololu STSPIN820 Stepper Motor Driver Carrier

This product is a carrier board or breakout board for the STSPIN820 stepper motor driver from STMicroelectronics. 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
• 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 Pololu A4988 stepper motor driver carriers in most respects
