A4988 StepStick Driver Module – 5-Pack with Heat Sinks for 3D Printers

Power your 3D printer, CNC, or engraving project with this set of A4988 StepStick stepper motor driver modules. Each compact board delivers precise microstepping and robust protection, designed to keep your motors running smoothly and reliably.

• Microstepping versatility: supports Full, 1/2, 1/4, 1/8, and 1/16-step subdivision for smooth, quiet motion and fine-tuned control.
• Robust drive capability: Up to 35V and +/- 2A output per channel, suitable for common hobbyist stepper motors used in 3D printers.
• Logic compatibility: Works with 3.3V or 5V logic signals, making it compatible with a wide range of controller boards and Arduino-based setups.
• Protective features: Built-in crossover-current protection, overheat shutdown, ground short-circuit protection, load short-circuit protection, and UVLO for reliable operation and motor safety.
• Efficient operation: Low RDS(on) output, automatic current decay mode testing/select, mixed slow decay mode, and synchronous rectification to minimize power loss and heat.
• What’s included: Package contains 5 A4988 StepStick Stepper Motor Driver Modules and 5 heatsinks for immediate cooling when mounted on compatible boards.
• Applications: Ideal for building 3D printers, CNC machines, engraving setups, and other essential motor-driven modules. Compatible with Arduino-based code and direct-drive motors; commonly used with printers similar to Prusa Mendel, Ultimaker, PrintBot, and MakerBot ecosystems.
• Origin and condition: Brand: AOKIN. Condition: New. Origin: Mainland China.
