Description
AI
The AEK-MOT-SM81M1 evaluation board is designed to drive a bipolar stepper motor in micro-stepping mode, with coil voltage monitoring for stall detection.
This application board features the automotive-grade L99SM81V stepper motor driver with embedded power MOSFETs and a comprehensive set of I/Os for MCU control and feedback signaling using SPI communication through a 12-pin male connector or two 5-pin connectors on the board.
The board is developed as part of the AutoDevKit initiative, and evaluation firmware is available for suitable microcontrollers such as the automotive-grade SPC5 series MCU on the AEK-MCU-C4MLIT1 control board.
