ULN2003 Stepper Motor Module
The ULN2003 high power chip drives the stepper motor
A, B, C, D LEDs indicate the state of the four-phase stepper motor when it is operating
Equipped with stepper motor standard interface, can be directly inserted when used.
The left of the IN1 ~ IN7 corresponding to the single-chip 7 IO line;
The right side of the white socket pin definition from top to bottom are VCC, A, B, C, D (then stepper motor common line, A phase, B phase, C phase, D phase);
The bottom of the 2-pin pin GND ground, V + then +5 V
Directly into the microcontroller development board or system board can be used, need to draw from the development board 4 IO port, 5V and ground.
The development board / system board and the motor drive board are connected by 6 DuPont lines
Drive Module Board Size:2.8cm x 2.8cm x 2cm
