A5984 Stepper Motor Driver Carriers

These carrier boards mate the Allegro A5984 driver to a 16‑pin socket or solderless breadboard via pre‑installed header pins, eliminating the need for hand soldering. Versions differ by current‑limit settings – ranging from 330 mA to 1.5 A depending on the supply voltage – and by the presence of an adjustable‑current option for fine‑tuning motor power. All models provide eight micro‑step resolutions down to 1/32‑step, built‑in over‑current and over‑temperature protection, and an adaptive decay algorithm that keeps the motor running smoothly under varying loads. The “Blue Edition” boards use a four‑layer PCB, improving thermal dissipation for higher‑current applications. These features make the carriers suitable for precise motion control in robotics, CNC, and other automation projects.
