The Stepper Motor NEMA‑17 (Adafruit model 324) is a bipolar stepper motor with 200 steps per revolution (1.8° per step), ideal for robotics, automation, and 3D printing projects. It operates at 12 V with a maximum current of 350 mA, compatible with controllers like the Adafruit Motor Shield or boards based on Arduino and CircuitPython.
It comes with a ready-to-use cable and a machined 5 mm shaft for easy attachment to gears or pulleys. Its 42 mm body fits most DIY projects and delivers a holding torque of 28 oz·in (≈20 N·cm), suitable for precision tasks. With a 4-wire connection, it's compatible with dual H‑bridge drivers.
