This is a breakout board for ON Semiconductor’s AMIS-30543 microstepping bipolar stepper motor driver, which features SPI-adjustable current limiting, 11 step modes (from full-step through 1/128-step), back-EMF feedback that can be used for stall detection or optional closed-loop control, and over-current and over-temperature protection. The board operates from 6 V to 30 V and can deliver up to approximately 1.8 A per phase without a heat sink or forced air flow (it is rated for 3 A per coil with sufficient additional cooling).

This product is a carrier board or breakout board for ON Semiconductor’s AMIS-30543 Micro-Stepping Motor Driver; we therefore recommend careful reading of the AMIS-30543 datasheet (495k pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 3 A output current per coil (see the Power Dissipation Considerations section below for more information). Here are some of the board’s key features:
  • Standard step and direction control interface
  • SPI interface for configuring settings (e.g. step mode, current limit, sleep) and reading status registers
  • Speed and load angle output that can be used for stall detection or closed-loop control of the torque and speed based on the load angle
  • Eleven different step modes: full-step (uncompensated, compensated 1-phase, or compensated 2-phase), half-step (uncompensated or compensated), 1/4-step, 1/8-step, 1/16-step, 1/32-step, 1/64-step, and 1/128-step
  • SPI-programmable current control (from 132 mA to 3 A) enables your microcontroller to adjust the peak-current limit on the fly as more or less torque or speed is needed
  • Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
  • Low-EMI PWM with SPI-selectable voltage slopes
  • Compatible with 5 V and 3.3 V microcontrollers
  • Integrated 5V regulator that can be used to supply an external microcontroller
  • Integrated watchdog function
  • Open coil detection
  • Thermal warning indicates when the driver is close to the thermal shutdown temperature
  • Over-current status and shutdown (short-to-ground and shorted-load protection)
  • Reverse voltage protection
