1. The main material of the product is plastic and copper, which is not easy to damage and has a long service life
2. This drive board is subdivided into 8 subdivisions, that is, each step of the motor is subdivided into 8 small steps, so that you can get more precise control, and it takes 1600 steps to complete a full 360 degree rotation.
3. Power supply range :7V ~ 30V Stepper motor driver size :1.89× 0.79× 0.35 inches; Compatible with :4, 6, 8-wire stepper motors of any voltage
4. Simply input the pulse to control the stepper motor, and the embedded converter can control the stepper motor.
5. The pwm current control circuit inside the chip can be set to slow, fast and mixed current attenuation modes through the voltage applied to the pfd. If the voltage at the pfd end is higher than 0.6vdd, the slow attenuation mode is selected. If it is below 0.21vdd, the fast attenuation mode is selected. In between is a mixed attenuation mode.
