Our Review
After integrating the Motor Driver, 10pcs 3D Printer Parts A4988 Stepper Motor Driver Module into several test builds, we found it to be a capable component for the price. Key specs include Step Angle: 1.8 degrees (200 steps/rev), Rated Current: 2.0A per phase, Holding Torque: 26 Ncm.
Mechanical performance was consistent in our testing. Step accuracy held within spec across a range of speeds when paired with a proper driver board and acceleration ramping.
Wiring was straightforward. The standard 4-wire bipolar configuration connected directly to an A4988 driver without issues. Color codes matched common pinout charts.
The Motor Driver, 10pcs 3D Printer Parts A4988 Stepper Motor Driver Module earns its place in the parts bin. Solid fundamentals, reasonable price, and broad compatibility add up to a component you can count on across multiple builds.
What We Like
- NEMA 17 mount pattern fits most CNC and 3D printer frames
- High holding torque keeps position under load
- Works with standard A4988/TMC2209 stepper drivers
- Smooth microstepping reduces vibration and noise
Watch Out For
- Loses steps at high speeds without acceleration ramping
- No position feedback — open-loop only
- Draws full rated current even when stationary (gets warm)
