The driver is based on an integrated ULN2003 circuit that contains several Darlington configurations. It works at very good parameters along with the stepper motor in the kit.
Step-by-step motors are often used in applications requiring precise motion control. You can meet them in 3D printers or normal printers, CNCs or robotic arms. In order to choose the right stepper for your application, see the data sheet to see the power consumption, engine speed and accuracy, torque and how to control it.
Use with Arduino
The picture shows a stepper motor and the ULN2003 driver card. It contains several Darlington transistors to send commands to each engine winding. In chapter DC Motors I explained how we can use a transistor to control a much higher current through a small current, applied on the basis of the transistor. A Darlington transistor consists of two common series-connected transistors in order to control as large a current as possible with a smallest command current.
This engine can also be powered from the 5V lead on the Arduino plate, but it is recommended to power from an external source.
