Stepper Gearmotor 5VDC 28BYJ-48-64
Originally designed for control of HVAC vanes and similar low-demand equipment, these stepper-motor gearboxes have lots of hacking potential. This is the higher-torque / lower speed 64:1 version.
This 28BYJ-48 is a 5V unipolar geared stepper motor, manufacted by the boatload for the HVAC control industry, where you’ll find these little units as actuators for airflow control in ducts and vanes.
Being a stepper motor, you’ll need a motor driver circuit.
It features a
- 5mm “Double-D” shaft,
- mounting lugs
- and nice 5-conductor 0.1″ pitch connector.
