Reviews

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).

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
