Driver for bipolar stepper motors with STEP/DIR interface, microstepping up to 1/16, soldered header pins and maximum current up to 1.5 A at 5 V or 1 A at 3.3 V. Pololu 5345
Description
Pololu 5345 designed for controlling bipolar stepper motors in electronics and robotics projects requiring precise motion control. The board is based on the A5984 chip from Allegro MicroSystems and operates with 3.3 V or 5 V logic, enabling direct connection to common microcontrollers.
Control is performed via the STEP/DIR interface, with supported modes including full step, half step and microstepping up to 1/16, allowing smooth motor operation. Current limiting is factory-set and depends on the logic supply voltage (VDD). With 5 V logic, the driver supports continuous current up to approximately 1.5 A per phase, while at 3.3 V logic up to approximately 1 A. The design does not include a potentiometer or any element for manual current adjustment.
The module features soldered header pins, allowing direct use with breadboards and prototyping systems without additional soldering. Motor power is supplied from a separate voltage source, independent of the logic supply. For operation above 1.2 A per phase, additional cooling such as a heatsink or forced airflow is required.
