Adafruit STSPIN220 Stepper Motor Driver Breakout Board

The Adafruit STSPIN220 Stepper Motor Driver Breakout Board offers easy, precise control of stepper motors with a simple GPIO-only interface. Just two output pins manage the DIRection and STEP functions, eliminating the need for timers or a PWM controller.

Key benefits include up to 1/256 microstepping for ultra-smooth motion and a user-friendly potentiometer to adjust current-limiting up to 1.3A. The board supports motor voltages from 1.8 to 10V and logic voltages from 3 to 5V, making it compatible with various microcontrollers, such as Arduino-compatible, ESP32, and Raspberry Pi.

For straightforward prototyping, it features terminal screw block connections and labeled pins, along with red, green, and yellow LEDs for real-time visual feedback on motor activity. It includes overcurrent protection and requires minimal soldering for header attachment.
