Product Introduction:
1. Driver Chip: A3967
2. MS1 and MS2 pins are used to control the motor subdivision (2, 4, 8), the default is 8 subdivisions
3. Compatible with 4, 6, and 8-wire stepper motors of any voltage
4. Adjustable current control 150MA-750MA can be adjusted by the potentiometer.
5. Power input range 7-30V, the higher the voltage, the higher the torque at high speed
6. This EasyDriver Stepper Motor Driver is a new Sparkfun imported stepper motor driver. It is easy to use and can be used with any device that can output 0-5V (3V please short circuit SJ2) pulse signal. EasyDriver powers the motor by connecting 7-30V voltage and can drive almost any stepper motor. EasyDriver's onboard voltage regulator chip can be set to 3.3V or 5V, can be directly connected to a 4-wire stepper motor, and the action of the stepper motor can be accurately controlled by the microcontroller.
Control:
●DIR -> Connect to pin 2
●STP -> Connect to pin 3
Power Supply:
● GND negative power supply
● M1 is the positive power supply for the motor
● GND negative power supply
● 5V chip power supply
● A B is the output port for the stepper motor
