This breakout board is for A4988 DMOS Microstepping Driver with translator and overcurrent protection. The Stepper motor allows users to operate bipolar stepper motors in full, half, quarter, eighth, and sixteenth step modes, with an output drive capactiy of up to 35V and 2A. The translator is the key to the easy implementation of the A4988. Simply inputting one pulse on the STEP input drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program.The A4988 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened.
Features
- Simple step and direction control interface
- Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
- Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated
