MODULE

A4988 / DRV8825 Stepper Motor Driver Expansion Board is Red A4988 Stepper Motor Driver Controller Board. It is made of superior material, safe and stable, great for 3D printers. A4988/DRV8825 can also be used, but pay attention to direction when inserting, otherwise, the driver may be burned down. A4988 / DRV8825 Stepper Motor Driver Expansion Board for 3D Printer Parts is use to extend the A4988 or DRV8825 stepper motor driver module.
Features:
-You can use A4988 / DRV8825, take care of the direction when inserting, or it may burn down the driver.
-The jumper hits the position of ON DP to indicate 16 subdivision (4988) or 32 subdivision (8825).
-White connector: for connection motor.
-Female Power connector: for connects 5V and 12V-24V power.
-E, S, D, respectively corresponding to the connection of the Enable/Step/Dir – drive signal output
