Description This product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver. This stepper motor driver lets you control one bipolar stepper motor at up to 2.2 A output current per coil (see the Power Dissipation Considerations section below for more information). Features Simple step and direction control interface Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay) Built-in regulator (no external logic voltage supply needed) Can interface directly with 3.3 V and 5 V systems Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout Short-to-ground and shorted-load protection 4-layer, 2 oz copper PCB for improved heat dissipation Exposed solderable ground pad below the driver IC on the bottom of the PCB Module size, pinout, and interface match those of the A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information) This product ships with all surface-mount components—including the DRV8825 driver IC—installed as shown in the product picture.
