The DRV8825 is a stepper driver by Texas Instruments which can be used as direct replacement for the Allegro A4988 driver as their connections are the same. The three key differences between them are that the DR8825 can deliver more current than the A4988 without additional cooling (1.5A vs 1A), it has higher maximum supply voltage (45V vs 35V), and it offers higher microstepping resolution (32 vs 16 microsteps).
