This breakout module has all the necessary components needed to make use of the stepper motor driver A4988 or DRV8825 driver carrier modules. You can adjust the NO switches to change the microstepping setting, following the driver datasheets.

Feed motor power to the VIN (or 9V in older version) pin to power up the stepper motor.

Note : Please insert the A4988/DRV8255 driver following the pin labels on the breakout module, inserting the module in reverse orientation will damage the driver carrier module when powered up. For DRV8825 driver module only, the +5V pin will be FAULT pin from the driver carrier module, so don’t connect 5V logic power to the +5V pin on the breakout module, only GND is needed to make common ground.
