Stepper motor set with motor and driver

This set consists of a 28BYJ-48 unipolar stepper motor and a matching ULN2003 driver module for small hobby projects. The motor plugs directly into the driver. The gearbox with a ratio of 1:64 has a certain deviation. If the motor always turns in the same direction, for example in a clock, this can lead to an error. With a light barrier module, the position can be redetermined from time to time and the start position determined at switch-on.

Recommended Accessories:

• Dupont Jumper Cable Set 30cm M/F 40 pcs.
• Light barrier module for speedometer / RPM measurement

Features:

• Unipolar with 4 phases
• 1:64 gearbox with a certain deviation
• Driver with 4 status LEDs for the windings
• Power on the driver is looped straight through, therefore only for small stepper motors
• Library: Stepper in the Library Manager

Application Examples:

• Clocks and pointers
• Small drives in model making
• Flaps and turntables
