Pin Configuration

Component Documentation: 17HS8401S NEMA17 Stepper Motor (48mm)
Pinout Explanation:
The 17HS8401S NEMA17 Stepper Motor (48mm) has a total of 8 pins, divided into two rows of 4 pins each. The pins are used to connect the motor to a driver or controller, which sends the necessary signals to rotate the motor. Here's a detailed explanation of each pin:
Row 1:
1. A+ (A_phase_positive): This pin is connected to the positive terminal of the A-phase coil of the stepper motor.
2. A- (A_phase_negative): This pin is connected to the negative terminal of the A-phase coil of the stepper motor.
3. B+ (B_phase_positive): This pin is connected to the positive terminal of the B-phase coil of the stepper motor.
4. B- (B_phase_negative): This pin is connected to the negative terminal of the B-phase coil of the stepper motor.
Row 2:
1. VCC (Motor Power Supply Positive): This pin is connected to the positive terminal of the motor power supply (usually 2.5V to 5V).
2. GND (Motor Power Supply Ground): This pin is connected to the negative terminal of the motor power supply (ground).
3. EN (Enable): This pin is used to enable or disable the motor driver. A logic high (e.g., 5V) enables the motor, while a logic low (e.g., 0V) disables it.
4. DIR (Direction): This pin is used to set the rotation direction of the motor. A logic high (e.g., 5V) sets the motor to rotate in one direction, while a logic low (e.g., 0V) sets it to rotate in the opposite direction.
Connection Structure:
To connect the pins, follow this structure:
1. Connect the A+ pin to the positive terminal of the A-phase coil driver.
2. Connect the A- pin to the negative terminal of the A-phase coil driver.
3. Connect the B+ pin to the positive terminal of the B-phase coil driver.
4. Connect the B- pin to the negative terminal of the B-phase coil driver.
5. Connect the VCC pin to the positive terminal of the motor power supply (e.g., 5V).
6. Connect the GND pin to the negative terminal of the motor power supply (e.g., GND).
7. Connect the EN pin to a digital output of your microcontroller or driver IC. Set this pin high (e.g., 5V) to enable the motor and low (e.g., 0V) to disable it.
8. Connect the DIR pin to a digital output of your microcontroller or driver IC. Set this pin high (e.g., 5V) to set the motor rotation direction and low (e.g., 0V) to set the opposite direction.
Important Notes:
Be sure to handle the stepper motor with care, as it can be damaged by excessive current, voltage, or heat.
Use a suitable motor driver or controller that can handle the current and voltage requirements of the 17HS8401S NEMA17 Stepper Motor.
Consult the datasheet and technical documentation of the motor driver or controller for specific connection and configuration requirements.
By following this documentation, you should be able to correctly connect and configure the 17HS8401S NEMA17 Stepper Motor (48mm) for your IoT project.
