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
Dimensions
- Size: 1.0″ × 1.2″
