The YKD2305M is a high-performance two-phase digital stepper driver recently developed by the Research and Development Center of China (RDC) based on next-generation 32-bit DSP technology. It features a drive voltage of DC 20V-50V, an adaptable current of up to 3A, and an outer diameter of 42~60mm.

Various models of two-phase hybrid stepper motors are available.
This driver utilizes a servo-like control principle, a unique circuit design, and superior software algorithm processing, enabling the motor to operate smoothly and with virtually no vibration or noise, even at low microstepping settings, providing a smooth and precise ride.

Current control technology significantly reduces motor heating; external 16-level constant torque microstepping with a maximum of 200 microsteps; optocoupler-isolated differential signal input; strong anti-interference capability; and overvoltage, undervoltage, and overcurrent protection.
