This is a dedicated aluminum heatsink designed specifically for the Raspberry Pi Compute Module 4(CM4). The heatsink is black and comes with a screw and thermal tape pack for attaching to your Compute Module 4. The mounting holes on the heatsink match the Compute Module mount holes perfectly. In testing, Waveshare found that the heatsink reduced temperatures by ~11C vs the bare CM4 board (your mileage may vary depending on usage and local conditions).

These extra pieces of Aluminum will ease and boost the cooling of your Stepper Motor Driver. The Aluminum Heatsink for A4988 DRV8825 Stepper Motor Driver features thermally conductive adhesive tape at its attaching side which helps cooling effect to occur more rapidly. The installation includes only removing the heatsink protection and sticking it by gently pressing the Aluminum Heat Sink against the Stepper Motor Driver. They are made up of Aluminum which is the good radiator of heat. These are very lightweight and handy heatsinks which show good heat dissipation property.
