UIM240XX are micro-high-performance stepping motor driver. Its biggest feature is the small size and the driving ability. They can be mounted onto NEMA 17/23/34/43 series stepping motor seamlessly through corresponding flanges. The UIM240L02 provide 0-2A adjustable peak current; UIM240C04 provide 1.5-4A adjustable peak current; UIM240C08 provide 3-8A adjustable peak current. Its high-speed current compensation can compensate for the impact caused by back-EMF when the motor is running at high speed. Besides UIM240L02 using 12-28VDC for supply, UIM240XX series drivers work on 12-38 VDC power supply. The enclosure is made of die-cast aluminum which provides a rugged, durable protection and improves the heat dissipation.

| Connection Port | ||
| Port | Symbol | Description |
| 1 | V+ | Positive Voltage: 12-48 VDC (Note: Max voltage is different between 242Lxx, 242Cxx and 242Hxx) |
| 2 | GND | Ground voltage: 0V (Positive and negative can not be wrong) |
| 3 | VCC | Common anode input, positive electrode of pulse, direction, and off-line signals is connected to the terminal |
| 4 | DIR | Direction signal input, High/ Low-level key for rotation direction control and vacancy for the high level |
| 5 | STP | Step pulse input, the falling edge is a valid pulse |
| 6 | ENA | Off-line signal input. Low level means the rotor in a free state, high or vacant means the motor be controlled |
