Product info

This StepStick is a carrier board or breakout board for Allegro A4988 Microstepping Driver with Translator and Overcurrent Protection and it is compatible with Pololu A4988 stepper driver

StepStick carrier board has all component need for A4988, so you can readily wire it with Arduino or RaspberryPi and control the stepper motor.

To operate this board, you need to have knowledge of A4988, therefore we recommend careful reading of the A4988 datasheet before using this product

StepStick Operation

StepStick [stepper motor driver] lets you control one bipolar stepper motor at up to 1.5 A output current per coil.

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.

A4988 Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO) and crossover current protection. Special power-Sort.

Current Ratting

A4988 can be configured up to 2A, for stable operation carrier board is designed for 1.5A configuration, so you can drive upto 1.5A with StepStick.
