The A4988 DRV8825 heatsink is a 9×9×12 mm aluminium heat sink designed to cool A4988 and DRV8825 stepper motor driver ICs on RAMPS boards and Arduino-based 3D printer controllers, preventing thermal shutdown during sustained high-current operation.

Stepper driver ICs like the A4988 and DRV8825 generate significant heat above 0.8 A. Without cooling, thermal overload protection triggers at around 150 °C, shutting down the stepper and halting your print. This A4988 DRV8825 heatsink attaches with a self-adhesive thermal pad and fits precisely over the driver chip package. As a result, sustained high-current printing becomes reliable without active cooling in most printer enclosures.

Key Features of the A4988 DRV8825 Heatsink

• Dimensions: 9 mm × 9 mm × 12 mm — sized for A4988 and DRV8825 chip footprints
• Aluminium with precision-cut fins for maximum surface area per footprint
• Self-adhesive thermal pad included — press-fit installation in seconds
• Suitable for A4988, DRV8825, TMC2208, and similar compact stepper drivers
• Also fits Raspberry Pi SoC, small ICs, memory chips, and transistors
• Prevents thermal shutdown during high-current stepper operation

Use Cases

• Cooling A4988 or DRV8825 drivers on a RAMPS 1.4 or Arduino MEGA shield
• Raspberry Pi SoC and USB controller thermal management in passively cooled cases
• Any small IC, memory module, or transistor requiring compact passive cooling
• CNC and automation projects with continuously running stepper drivers

Works Well With

• Nema17 Bipolar Stepper Motor 1.8° — the Nema17 stepper this driver typically controls in 3D printer and CNC builds
• Nema17 Stepper Heatsink — Black Anodised — a matching Nema17 body heatsink to cool the motor alongside the driver
