A4988 Stepper Motor Driver IC (SMD Package)

Every A4988 breakout module already in the catalog carries this same chip, soldered onto a small board with its support components already wired in, which is exactly right for most hobby projects but gets in the way the moment someone wants to design their own driver board from scratch. This bare SMD-package A4988 is that same proven microstepping driver silicon on its own, ready to be reflowed directly onto a custom PCB layout rather than tied to a fixed breakout footprint.
