UIM24302 is a miniature high-performance step motor driver with built-in pulse generator. It has the characteristics of small size, strong drive ability. With the corresponding flange, it can be directly fixed on the step motor of 42/57 series. Its thickness is less than 14mm. UIM24302 can provide 0-2A adjustable peak current. The user can adjust the speed by adjusting the resistor after power on, and it will turn immediately without the participation of the upper computer. At the same time, it has a high-speed current compensation function, which can compensate for the influence of the back EMF caused by the high-speed rotation of the motor. UIM24302 uses 10V-35V DC power supply.
This manual introduces the UIM24302 intelligent pulse‑integrated stepper motor driver, highlighting its small size (42.3 mm × 42.3 mm × 13.5 mm) and built‑in pulse generator. It explains how the driver can be mounted directly on compatible stepper motors and operated without a host controller.
The guide details the wiring ports, connection diagrams, adjustable current settings, speed control, and safety notices. Performance tables list supply voltage, output current, microstepping, temperature ranges, and other electrical characteristics. This manual is written in Chinese.

The driver operates from 10 V to 35 V DC.
Direction is set by the DIR pin; a high or low level selects forward or reverse, and a floating input is treated as high.
It can generate step frequencies from 10 pps up to 48 000 pps (approximately 0.2 rpm to 900 rpm for a 1.8° motor).
