Our Review
After integrating the A4988/DRV8825 Module CNC 3D Printer Parts Accessory Reprap pololu Stepper Motor Driver Module with Heatsink for ramps 1.4 Proactive(A4988 Green) 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: 0.4A 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.
For the price point, the A4988/DRV8825 Module CNC 3D Printer Parts Accessory Reprap pololu Stepper Motor Driver Module with Heatsink for ramps 1.4 Proactive(A4988 Green) delivers what you need without unnecessary complexity. Recommended for hobbyists and engineers working on projects where motors & actuators components are essential.
What We Like
- High holding torque keeps position under load
