Driver DRV8825, respectively. stepper motor driver for 3D printers include the latest generation of drivers. It can divide one step motor (who has a typically 200 per shaft revolution) for another 32 intermediate steps. The side-effect of this regime is reduction noise stepper motors.
The driver is suitable for use with an electronic control board RAMPS 1.4 and MEGA2560. Used to control stepper motors in a 3D printer, CNC machines and various robots.
