keyestudio 5V stepper motor driver module + stepper motor

This Keyestudio 5V stepper motor and driver module kit is an ideal choice for South African students, makers, and hobbyists looking to learn precise motion control. It features a 28BYJ-48 stepper motor paired with a driver board, making it simple to interface with microcontrollers for robotics and automation projects.

Precise open-loop positioning

The motor operates reliably in an open-loop control system, meaning you do not need expensive optical encoders or feedback sensors to track its position. Your controller simply keeps track of the input step pulses to determine the exact location of the shaft.

Proportional speed and rotation

The rotation angle of the motor is directly proportional to the number of input pulses, while the rotational speed is proportional to the frequency of those pulses. This allows you to achieve a wide range of speeds and highly predictable movements.

Full torque and non-cumulative accuracy

This stepper motor delivers full torque even at a standstill as long as the windings are energized. It offers excellent repeatability with a step accuracy of 5 percent, and this error is non-cumulative from one step to the next.

Brushless design for reliable operation

Because there are no contact brushes inside the motor, wear and tear is significantly reduced. The overall lifespan of the motor is primarily dependent on the durability of its internal bearings.

Technical specifications and ratings

Operating at a rated voltage of 5VDC, this 4-phase stepper motor features a 1/64 speed variation ratio and a stride angle of 5.625 degrees divided by 64. It provides an in-traction torque of over 34.3 mN.m at 120Hz and a DC resistance of 50 ohms.

Synchronous rotation and responsive control

The motor provides excellent response to starting, stopping, and reversing commands. You can also achieve very low-speed synchronous rotation when a load is coupled directly to the shaft.
