Note that the STEP and DIR pins are not pulled to any particular voltage internally, so you should not leave either of these pins floating in your application. See product page to backorder. This hybrid bipolar stepping motor has a 1. Motor connections Four, six, and eight-wire stepper motors can be driven by the DRV if they are properly connected; a FAQ answer explains the proper wirings in detail. The driver requires a logic supply voltage 3 — 5. Using the driver Minimal wiring diagram for connecting a microcontroller to an A stepper motor driver carrier full-step mode.

See product page to backorder. The stepper motor itself has a 1. For customers interested in higher volumes at lower unit costs, we offer a bulk-packaged version without header pins and a bulk-packaged version with header pins installed. Dimensions The following diagram shows the stepper motor dimensions in mm. Pololu stepper details about these power states, see the datasheet. One way to set the current limit is to put the driver into full-step mode and to pololu stepper the current running through a pollolu motor coil without clocking the STEP input.

Pololu – DRV Stepper Motor Driver Carrier, High Current

Bipolar stepper motor wiring diagram. Shop Blog Forum Support.

These modules are generally basic carrier boards for a variety of stepper motor driver ICs that offer low-level interfaces like inputs for directly initiating each step.


A microstepping driver such as the A allows higher poololu by allowing intermediate pololu stepper locations, which are achieved by energizing the coils with intermediate current pololu stepper.

Also, if the supply voltage is very high compared to pololu stepper the motor needs to achieve the set current, the duty cycle will be very low, pololu stepper also leads to significant differences between average and RMS currents.

The headers can be soldered in for use with solderless breadboards or 0. polol

Shop Blog Forum Support. Products New Products Pololu stepper This carrier board uses low-ESR ceramic capacitors, which makes it susceptible to pollu LC voltage spikesespecially when using power leads longer than a few inches.

Stepper Motor: Bipolar, 200 Steps/Rev, 35×28mm, 10V, 0.5 A/Phase

For customers interested in higher volumes steppper lower unit costs, we offer a pololu stepper version without header pins and a bulk-packaged version with pololu stepper pins installed. Products New Products Specials! This hybrid bipolar stepping motor has a 1. The current limit relates to the reference voltage as follows:.

Products New Products Specials! This stepper motor driver lets you control one bipolar stepper motor at up to 2.

Since pololu stepper input voltage to the driver can be significantly higher than the pololu stepper voltage, the measured current on the power supply can be quite a bit lower than the coil current the driver and coil basically act like a switching step-down power supply.

Also, note that you will need to perform this adjustment again if you ever change the logic voltage, Vdd, since the reference voltage that sets the pololu stepper limit is a function of Vdd.

Stepper Pololu stepper Applications Stepper motors are generally used in a variety of applications where precise position control is desirable and the cost or complexity of a feedback control system is unwarranted. Here are a few applications where stepper motors are often found:.

Installing the pololu stepper 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.

In particular, increasing the voltage generally allows for higher step pokolu and stepping torque since the current pololu stepper change more quickly in the coils after each step. For more information, please see the frequently asked questions.
