Introduction
The DRV8825 stepper motor driver carrier is the breakout board for TI's DRV8825 microstepping bipolar stepper motor driver.
feature:
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
Can directly interface with 3.3 V and 5 V systems
Over-temperature thermal shutdown, over-current shutdown and under-voltage lockout
Ground short-circuit and load short-circuit protection
4-layer 2 oz copper PCB for improved heat dissipation
Exposed solderable ground pad under the driver IC on the bottom of the PCB
The module size, pinout and interface match in most aspects with our A4988 stepper motor driver carrier (for more information, please see the bottom of this page)
Adjustable current control allows you to use a potentiometer to set the maximum current output, allowing you to use a voltage higher than the rated voltage of the stepper motor to achieve a higher step rate
Intelligent chopper control, automatically select the correct current attenuation mode (fast decay or slow decay)
45 V maximum supply voltage
Built-in voltage regulator (no need for external logic voltage supply)
This module has almost the same pins and interfaces as our A4988 stepper motor driver carrier, so it can be used as a direct substitute for higher performance of these boards in many applications.
The DRV8825 has adjustable current limit, overcurrent and overheat protection, and six microstep resolutions (down to 1/32 steps). Its operating voltage is 8.2 – 45 V, and each phase can provide up to about 1.5 A of current without the need for a radiator or forced air flow (each coil has a rated current of up to 2.2 A and has enough additional cooling).
A4988
This product is a breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection; please read the A4988 datasheet carefully before using this product. This stepper motor driver lets you to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes, with an output drive capacity of up to 35 V and 2 A.

The translator is the key to the easy implementation of the A4988. Simply inputting one pulse on the STEP input drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program.The A4988 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened.
