Pololu A4988 compatible stepper drivers. (A4988, DRV8825 and others)
The A4988 is a microstepping driver for controlling bipolar stepper motors which has built-in translator for easy operation.
Microstepping can divide a motor’s basic step up to 256 times. Microstepping improves low speed smoothness and minimizes low speed resonance effects.
Microstepping produces roughly 30% less torque than dual phase full stepping
