This advanced closed-loop stepper motor controller features a 32-bit ARM Cortex-M0+ processor and a 14-bit magnetic encoder for precise position, speed, and torque control. It utilizes Field-Oriented Control (FOC) to achieve low noise, minimal vibration, and reduced heat. The high-efficiency 4 half-bridge driver with 8 MOSFETs ensures reliable performance at high speeds without losing steps. Flexible microstepping from 1 to 256 subdivisions (including odd values like 11) allows smooth motion.
