Product includes:
1. 5 pieces * DRV88252
Offer heatsink for free
Compare with 4988
1. 2.5A max
2. Supports 32 micro step
3. 4-layer PCB, 2oz copper, good heat dissipation
4. Internal resistance of chip is smaller and produces lower heat, which is conducive to heat dissipation
Caution:
Notice the direction when install, otherwise, driver will be broken
Overview:
This product is carrier board or breakout board for TI’s DRV8825 stepper motor driver, we therefore recommend careful reading of the DRV8825 datasheet (1MB pdf) before using this product
This stepper motor driver lets you control one bipolar stepper motor at up to 2.2A output current per coil (see the power dissipation considerations section below for more information)

Here are some of the driver’s key features:
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 potentiometer, which lets you use voltage above your stepper motor’s rated voltage to achieve higher step rates
4. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
5. 45V maximum supply voltage
6. Built-in regulator (no external logic voltage supply needed)
7. Can interface directly with 3.3V and 5V systems
8. Over-temperature thermal shutdown, over-current shutdown and under-voltage lockout
9. Short-to-ground and shorted-load protection
10. 4-layer, 2 oz copper PCB for improved heat dissipation
11. Exposed solder able ground pad below the driver IC on the bottom of the PCB
12. Module size, pin out, and interface match those of our A4988stepper motor driver carriers in most respects (see the bottom of this page for more information)
We also carry a DRV8824 stepper motor driver carrier that can serve as a direct substitute for the DRV8825 carrier when using lower-current stepper motors
DRV8824 can only deliver up to 0.75A per coil without heatsink (1.2A max with proper cooling), but it has larger current-sense resistors that allow for better micro stepping performance than the DRV8825 carrier at low current
Only way to tell our DRV8824 carrier apart from the DRV8825 carrier is by the markings on the driver IC, if you have a mix of the two, you might consider marking them (there is a blank square on the bottom silkscreen you can use for this)
For lower-voltage applications, consider our pin-compatible DRV8834 carrier, which works with motor supply voltages as low as 2.5V
This product ships with all surface-mount components-including the DRV8825 driver IC-installed as shown in picture
