Thanks to Texas Instruments' unipolar stepper DRV8805PWP stepper motor driver, you can ensure that your pumps and actuators are operating at their optimal setting. With an output that has a voltage of -0.3 to 65 V, this is power management at its best. In order to ensure parts aren't damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. This device has a minimum operating supply voltage of 8.2 V and a maximum of 60 V. This motor controller has an operating temperature range of -40 °C to 85 °C.
