Description
A3967 EasyDriver Stepper Motor Driver
The A3967 EasyDriver is a microstepping driver board for compatible stepper motors. It accepts step and direction control signals from a microcontroller and provides switched current to the motor phases. This listing is for the driver board; the stepper motor is not included unless the selected offer says otherwise.
Specifications stated in the listing
- Driver IC: A3967
- Compatible motor wiring: 4, 6 or 8 wires
- Driver supply range: 6–30 V
- Adjustable phase-current range stated: 150–700 mA per phase
- Microstepping settings via MS1 and MS2: full, half, quarter and eighth step
- Default microstep setting stated: eighth step
The source listing’s wording around the current range is unclear; confirm the exact board revision and current-setting instructions before use. Set the driver current limit to suit the motor and provide appropriate cooling. Do not connect or disconnect a stepper motor while the driver is powered. Higher supply voltage may help maintain torque at higher speeds within the motor and driver limits; it does not override the current setting or ratings.
Typical applications
- Arduino and microcontroller stepper projects
- CNC and positioning mechanisms
- Robotics and automation prototypes
- Small 4-, 6- or 8-wire stepper motors
