It defaults to 1/16 microstepping and supports up to 1/256 microstepping via mode pin configuration, making it ideal for smooth, precise motion in low-voltage applications.\n\nDesigned for prototyping, the board features screw terminal blocks for motor power and stepper wires, labelled control pins, mounting holes, and LED indicators for direction and step activity. An onboard potentiometer sets the current limit up to ~1.3A.\n\nKey Features\n\n\nSTSPIN220 Driver – 1.8–10V motor voltage, up to 1.3A per coil\n\nUp to 1/256 Microstepping – Default 1/16; configurable via DIR/STEP/MS1/MS2 pins on reset\n\nGPIO-Only Control – No timers, PWM, or UART needed — just DIR and STEP pins\n\n3–5V Logic – Works with Arduino, ESP32, Raspberry Pi, and more\n\nCurrent Limit Potentiometer – Adjustable up to ~1.3A\n\nLED Indicators – Red/green for direction, yellow for step activity\n\nScrew Terminal Blocks – For motor power and 4-wire bipolar stepper (20–26 AWG)\n\nOvercurrent Protection – Built into the driver chip\n\n47 µF 16V Capacitor – On motor power rail\n\nFour Mounting Holes – Easy to secure in enclosures\n\n\nIdeal For\n\nLow-voltage stepper motor projects (1.8–10V)\nCNC machines and 3D printers\nRobotics and precise positioning\nPrototyping with bipolar stepper motors\n\n\nPackage Contents\n\n1× STSPIN220 stepper driver breakout (assembled and tested)\n1× Header strip\n\n\n\nNote: Some soldering required to attach headers. Microcontroller, stepper motor, and power supply not included. A heatsink may be needed at higher currents (not included).\n\n\nResources\n\nSTSPIN220 Datasheet\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":303,"title":"Default Title","sku":"AF-6353","mpn":"ADA6353","price":11.33,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
