Smart Electronics~5V stepper motor 4-phase 5-wire stepper motor 28BYJ-48-5V stepper motor/deceleration motor
It is a normal phenomenon that the rotating head of the motor can not be rotated by hand. It needs to be driven by a single chip computer. Please know. Deceleration stepper motor Diameter: 28mm Voltage: 5V Stepping angle: 5.625 x 1/64 Deceleration ratio: 1/64 5-wire 4-phase can be driven by ordinary ULN2003 chip or connected into 2-phase. It can be used with development board. It can be directly plugged in to facilitate the use of stepper motor on development board.
