DRV8824 Stepper Motor Driver Carrier, Low Current
This is a breakout board for TI’s DRV8824 microstepping bipolar stepper motor driver, a lower-current version of the DRV8825. It can deliver up to 0.75 A per coil without a heat sink (it is rated for up to 1.2 A per coil with sufficient additional cooling), and it has larger current-sense resistors than the DRV8825 that allow for improved microstepping performance at low currents. This board ships with 0.1″ male header pins included but not soldered in.
his product is a carrier board or breakout board for TI’s DRV8824 stepper motor driver; we therefore recommend careful reading of the DRV8824 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 1.2 A output current per coil.
Here are some of the driver’s key 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)
- 45 V maximum supply voltage
- 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 our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information)
The DRV8824 stepper motor driver carrier ships with one 1×16-pin breakaway 0.1" male header. The headers can be soldered in for use with solderless breadboards or 0.1" female connectors. You can also solder your motor leads and other connections directly to the board.
The driver requires a motor supply voltage of 8.2 – 45 V to be connected across VMOT and GND. This supply should have appropriate decoupling capacitors close to the board, and it should be capable of delivering the expected stepper motor current.
