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 (1MB pdf) before using this product. 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).
-
Suitable for 8.2V~45V (between VMOT and GND for motor), and less than 2.2A (2A for A4988) steppers
-
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 (N/A for A4988)
-
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 , pinout, and interface match those of our A4988 stepper motor driver carriers in most respects.
