ULN2003 Stepper Motor Driver Board, 5V 4-Phase, 5 Pack

This 5-piece ULN2003 driver board set is designed for 4-phase stepper motor control projects that use a DC5V power input. Each compact PCB board is built around the ULN2003 driver chip and includes A, B, C, and D indicator LEDs, making it easier to view the active phase state while the motor is running. The standard motor interface allows a compatible five-wire four-phase stepper motor to be connected directly, while IN1 to IN4 connect to microcontroller IO pins for control. The board also includes extra output pins for expansion in small automation, electronic learning, and DIY control applications where a compact stepper driver module is needed. Specifications: Rated Voltage: DC5V 4-phase Size: 3.5 x 3.2cm / 1.38 x 1.26in Weight: 6g Material: PCB Color: Multicolor Wiring method: 1.+connected to positive 5V, 2.- connected to negative pole, 3.IN1-IN4 connected to microcontroller IO, 4.white terminal block inserted into five wire four phase stepper motor. Package included: 5 x Motor Driver Boards Notes: 1. The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness. 2.
