1.A4988 driver
This product is a carrier board or breakout board for Allegro's A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection by Pololu; we therefore recommend careful reading of the A4988 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil.
2.Heatsink
This 8.5x8.5x5mm heatsink, purchased for use with the pololu A4988 drivers, despite their tiny size they are still very large when placed on the driver, may require machining to fit on the Pololu drivers but if careful with soldering and it clears the SMD resistors I don't see the need for any modification.
3.Heatsink Mount Sticker
The 25mm X 25mm sticker is used to paste your heatsink on the chip of the driver.Every sticker can be cut into 4 pieces to paste 4 pcs heatsinks.
