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 - \u003cem\u003eor \u003c\/em\u003eyou could take the easy way out and use an\u003cstrong\u003e Adafruit STSPIN220 Stepper Motor Driver Breakout Board\u003c\/strong\u003e, which makes controlling stepper motors easy-breezy, with a simple GPIO-only interface.\u003c\/p\u003e\n\u003cp\u003eAll you need is two output pins: no timers, PWM, or a real-time microcontroller. Set the DIRection pin high or low to set the spin orientation. Then, toggle the STEP pin to take one step or microstep at a time. By default the board is configured for 1\/16 microsteps per toggle. However, if you want to connect the RESET pin and the two mode pins, you can set anywhere from 1, 1\/2, 1\/4, 1\/8, 1\/16, 1\/32, 1\/64, 1\/128 or even 1\/256! The microstep mode is determined by the DIR\/STEP\/MS1\/MS2 pin states when coming out of reset. The step\/microstep mode can be adjusted on the fly! LEDs on the DIR and STEP pins let you get visual feedback of your motor signal.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWe stock quite a few of these \"DIR\/STEP\" stepper drivers - each with it's strengths!

Often it comes in \"3D printer breakout\" designs: those breakouts are great for plugging into motherboards, but are a little tough to use for prototyping. Our version comes with terminal blocks for the motor power and stepper wires, plus nicely labeled pins for control and mounting holes.\u003c\/p\u003e\n\u003cp\u003eThis driver has built in current-limiting capability To use the current limiting capability, twist the onboard potentiometer: when all the way to the right we can get to up to 2A max. Note that the higher the currents will heat up both the motor driver and stepper so you may need to add heatsinking to the chip.
