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, allowing the use of higher voltages for increased step rates Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay) Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout 4-layer, 2 oz copper PCB for improved heat dissipation This product is a carrier board or breakout board for TI's DRV8834 low-voltage stepper motor driver. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil (see the Power Dissipation Considerations section below for more information). 2.5-10.8 V supply voltage range. Built-in regulator (no external logic voltage supply needed). Can interface directly with 3.3 V and 5 V systems. Short-to-ground, short-to-supply, and shorted-load protection. Exposed solderable ground pad below the driver IC on the bottom of the PCB. This product ships with all surface-mount components-including the DRV8834 driver IC-installed as shown in the product picture. Color: As Shown Material: PCB Package Contents: 1 set of DRV8834 Low-Voltage Stepper Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
