Description：
The DRV8825 stepper motor driver carrier is a breakout board
for TI's DRV8825 microstepping bipolar stepper
motor driver. The module has a pinout and interface that
are nearly identical to those of our A4988 stepper motor
driver board， so it can be used as a higher-performance
drop-in replacement for those boards in many applications.
The DRV8825 features adjustable current limiting，
overcurrent and overtemperature protection， and six microstep
resolutions (down to 1/32-step). It operates from 8.2 – 45 V
and can deliver up to approximately 1.5 A per phase without a
heat sink or forced air flow (rated for up to 2.2 A per coil with
sufficient additional cooling).

Simple step and direction control interface
1.Simple step and direction control interface
2.Six different step resolutions: full-step， half-step， 1/4-step，
1/8-step， 1/16-step， and 1/32-step
3.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.
4.45 V maximum supply voltage
5.Built-in regulator (no external logic voltage supply needed)
6.Can interface directly with 3.3 V and 5 V systems
7.Over-temperature thermal shutdown， over-current shutdown， and under-voltage
lockout
8.Short-to-ground and shorted-load protection
9.4-layer， 2 oz copper PCB for improved heat dissipation
10.Exposed solderable ground pad below the driver on the bottom of the PCB
11.Module size， pinout， and interface match those of our A4988 stepper motor driver carr
iers in most respects
