ULN2003 stepper motor driver board
ULN2003 Stepper Motor Driver Board: ULN2003 Darlington using high-power stepper motor driver chip. A, B, C, D four-phase LED indicates the status of the stepper motor work. Stepper motor with a standard interface, when used directly pluggable. Drive Module Board Size:35mm x 31mm x 11mm The wiring method for stepping motor: Left 1 N 1 ~ 1 N 4 connect to the four corresponding IO wires of MCU. The right black pins are defined from top to VCC,A,B,C,D ( connect to the concentric line,phase A,B,C,D of stepping motor)s. The wiring method for DC motor: Left 1 N1 ~ 1 N 4 connect correspondingly to the four IO wires of MCU The right black pins are defined as:below is VCC Power supply method: Connect short circuit hat,choose 5V as the working voltage for stepping motor/DC motor. Take off short circuit hat,stepping motor/DC motor can choose external voltage for power supply via pins.
