5-Piece A4988 Stepper Motor Driver Module Set with Heat Sinks

Manufacturer: hiBCTR / Generic Aftermarket

Cost-effective 5-pack of reliable A4988 stepper drivers, each with pre-attached aluminum heatsink. Ideal for repairs, upgrades, or building 3D printers, CNC machines, and Arduino-based motion projects.

Features

• 5-Piece Set: Ready for multi-axis use or as spares
• Integrated Aluminum Heatsinks: Prevents thermal shutdown during long operation
• Broad Compatibility: Works with RepRap (Mendel/Huxley), Arduino CNC shields, and similar systems
• Microstepping: Up to 1/16 steps for smoother motion than full-step
• Adjustable Current Limit: Onboard potentiometer for safe motor matching

Benefits

• Economical full-axis upgrade or repair kit
• Reliable long-duration performance with good cooling
• Versatile for 3D printing, CNC, robotics, and DIY projects
• Finer control and reduced vibration via microstepping

Compatibility & Important Notes

• Primary Use: RepRap 3D printers, Arduino CNC shields, motion control projects
• Voltage Range: 8V–35V (match to your motors and PSU)
• Critical: Always set current limit (Vref) correctly to avoid damage to drivers/motors
