StepStick A4988 & DRV8825 Stepper Motor Driver with Heat Sink Carrier
Upgrade your 3D printer with precision stepper motor drivers compatible with the popular RAMPS 1.4 control board. Whether you're building a RepRap, upgrading an existing machine, or prototyping a CNC project, these compact driver modules deliver reliable, smooth motor control for all your axes.
Why Choose This Stepper Motor Driver?
- Dual Compatibility: Supports both the A4988 and DRV8825 stepper motor driver ICs — choose the right chip for your project's current and microstepping requirements.
- Heat Sink Included: Comes with an adhesive aluminum heat sink carrier to help manage operating temperatures and keep your driver running stably during long print sessions.
- RAMPS 1.4 Ready: Plug-and-play compatibility with RepRap RAMPS 1.4 boards and most standard 3D printer controller boards (4-pin stepper header layout).
- Wide Temperature Range: Rated for operating temperatures from -40°C to 80°C, making it suitable for a wide range of environments and enclosures.
- Supply Voltage: Supports up to 1A (A4988) or 2.5A (DRV8825) motor current, giving you flexibility for different stepper motor configurations.
- SMD Construction: Surface-mount components ensure a compact, low-profile module that fits neatly on your printer's mainboard.
- Microstepping Support: Achieves up to 1/16 microstepping (A4988) or 1/32 microstepping (DRV8825) for ultra-smooth motor movement and improved print quality.
- Condition: Brand new — every unit ships fresh from the factory.

Frequently Asked Questions
Q: Is this stepper motor driver compatible with RAMPS 1.4 and RepRap printers?
A: Yes! Both the A4988 and DRV8825 stepper motor driver modules are designed to be fully compatible with RAMPS 1.4 boards and most RepRap-based 3D printer controllers. They use the standard 4-pin stepper driver header layout, so installation is straightforward — just plug in and configure your firmware current settings.
Q: What is the difference between the A4988 and DRV8825 drivers?
A: The A4988 supports up to 1A motor current and 1/16 microstepping, making it ideal for lighter-duty stepper motors. The DRV8825 supports up to 2.5A motor current and finer 1/32 microstepping, offering smoother motor movement and compatibility with more powerful stepper motors. Both include a heat sink to help manage thermal output.
Q: Does the heat sink come pre-applied or do I need to attach it myself?
A: The heat sink comes with an adhesive backing and is simple to attach to the driver IC. It is recommended to apply the heat sink before extended use to help maintain stable operating temperatures, especially in enclosed printer builds.
Q: How many driver modules are included per order?
A: Each order includes 1× stepper motor driver module along with its corresponding heat sink. If you need multiple drivers for all axes (X, Y, Z, E), simply add the required quantity to your cart.
