Our Review
The 42 Stepper Motor Driver Expansion Board DRV8825 A4988 3D Printer Control Shield Module for Arduino UNO R3 Ramps1.4 Proactive delivers solid performance for its category. With Step Angle: 1.8 degrees (200 steps/rev), Rated Current: 1.5A per phase, Holding Torque: 65 Ncm, it covers the essentials that most makers and engineers need for their projects.
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 42 Stepper Motor Driver Expansion Board DRV8825 A4988 3D Printer Control Shield Module for Arduino UNO R3 Ramps1.4 Proactive 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
- Smooth microstepping reduces vibration and noise
- Reliable bipolar winding configuration for consistent torque
- Affordable replacement for 3D printer and CNC upgrades
- Works with standard A4988/TMC2209 stepper drivers
Watch Out For
- Draws full rated current even when stationary (gets warm)
- Loses steps at high speeds without acceleration ramping
- Wire color coding varies between manufacturers
