This product ships with all surface-mount components-including the DRV8825 driver IC-installed as shown in the product picture. The Black Edition A4988 stepper motor driver carrier is a higher performance version of our original A4988 carrier.

The MP6500 carrier can deliver up to 1.5 A per phase (continuous) without a heat sink and is available in two versions, one with a pot for controlling the current limit and one with digital current limit control for dynamic current limit adjustment by a microcontroller.The DRV8880 carrier offers dynamically scalable current limiting and “AutoTune”, which automatically selects the decay mode each PWM cycle for optimal current regulation performance based on factors like the motor winding resistance and inductance and the motor’s dynamic speed and load.The DRV8834 carrier works with motor supply voltages as low as 2.5 V, making it suitable for low-voltage applications.Note that we carry several other stepper motor drivers that can be used as alternatives for this module (and drop-in replacements in many applications): Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information).Exposed solderable ground pad below the driver IC on the bottom of the PCB.4-layer, 2 oz copper PCB for improved heat dissipation.Short-to-ground and shorted-load protection.Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout.Can interface directly with 3.3 V and 5 V systems.Built-in regulator (no external logic voltage supply needed).Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay).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.Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step.Simple step and direction control interface.Here are some of the driver’s key features: 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). This product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver we therefore recommend careful reading of the DRV8825 datasheet before using this product. DRV8824/DRV8825 stepper motor driver carrier with dimensions.
