Description:
The A4988 is a complete micro-stepping motor driver with built-in translator for easy operation. Includes a fixed off time current regulator, regulator in slow or mixed dampening mode. The A4988 converter is the key to make implementation easier. As long as you have a "one step" input, the motor will drive 1 micro step. Phase sequence not available here.
Features:
Simple step and direction control interface, ground circuit and load short-circuit protection. Five different step resolutions: full step, half step, quarter step, 8 step and 16 steps. Intelligent chopping control that automatically selects the appropriate current attenuation mode (fast attenuation or slow decay. Overheating thermal shutdown, undervoltage lockout, crossover current protection Adjustable current control allows you to set the maximum current output. The potentiometer motor rated voltage can be used above the stepper to achieve a higher step rate. Internal synchronization Rectifier control circuits provided to improve pulse width Power consumption of Modulation (PWM) operation.
