This advanced closed-loop stepper motor controller features a 32-bit ARM processor with a 14-bit magnetic encoder, delivering precision and reliability for 3D printers and CNC applications. It integrates position, speed, and torque closed-loop control to ensure high-speed operation without step loss. Field-Oriented Control (FOC) minimizes noise, vibration, and heat generation. The high-efficiency 4 half-bridge driver uses 8 MOSFETs for optimal performance. The 14-bit magnetic encoder provides accurate angle resolution of 0.08 degrees. Flexible microstepping supports 1 to 256 subdivisions, including odd values like 11, for smoother motion.
