Stepper motors are used for CNC machines, 3D printers, and whenever else one needs precise, powerful motion. But to get good behavior from steppers, you need a motor driver chip that can provide high bursts of current, and for smooth motion, be able to PWM that current for microstepping support. You can DIY this with a lot of timers, a microcontroller, and an H-Bridge chip - or you could take the easy way out and use an Adafruit STSPIN220 Stepper Motor Driver Breakout Board, which makes controlling stepper motors easy-breezy, with a simple GPIO-only interface. https://elecena.pl/product/28942248/adafruit-stspin220-stepper-motor-driver-breakout-board 2025-06-12 https://elecena.pl/product/28942248/adafruit-stspin220-stepper-motor-driver-breakout-board 2026-01-29
