Power connections The driver requires a motor supply voltage of 8.2 – 45 V to be connected across VMOT and GND. Using the driver Minimal wiring diagram for connecting a microcontroller to a DRV8824/DRV8825 stepper motor driver carrier (full-step mode). If you plan on installing the header pins in this orientation, please set the current limit before soldering in the pins. Caution: Installing the header pins so that the silkscreen side is up and the components are down can limit the range of motion of the trimpot used to set the current limit. 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). This product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver we therefore recommend careful reading of the (1MB pdf) before using this product. This version of the DRV8825 Stepper Motor Driver Carrier ships with 0.1″-pitch male header pins installed as shown in the main product picture, so no soldering is required to use it with an appropriate 16-pin socket or solderless breadboard.
