Stepper motor 28BYJ-48 12V unipolar

Low-cost stepper motor for 12V. This model is normally used in the manufacturing of air-conditioners, automatic window blinds and other applications where high torque is more important than high speed. The motor is internally geared with a ratio of about 64:1 (more precisely 63.68395:1).

The motor can be used together with all stepper motor drivers for unipolar motors. The red wire should then be connected to ground (GND), orange/pink to M1 (or similar) and blue/yellow to M2 (or similar). Can also easily be driven by discrete transistors or a darlington driver (ULN2003).
