StepDrive P3

3x Stepper Motor Driver

---

Overview

This module utilizes the very common stepper motor drivers commonly used in Arduino CNC Shield. They are available in multiple models. We include drivers capable of 30V @ 1A each, but you can easily swap them with your favorite driver if desired.

Key features • 3x stepper motor control • Terminal Block Connectors • 77x42mm Overall Dimension

🌿 Cables not included

Modules ship without cables to reduce waste. Some specialty boards include a USB cable; for the rest, see Cables to add cables to your order.

Commands

Function	Description
DVer()	This driver version.
init(x)	Init motors with resolution x: 0: 1/8 step, 1: 1/2 step (default), 2: 1/4 step, 3: 1/16 step.
step_m1(d,c)	Run motor M1 with d: direction, c: steps.
step_m2(d,c)	Run motor M2 with d: direction, c: steps.
step_m3(d,c)	Run motor M3 with d: direction, c: steps.
set_m(m, d, c)	Set motor in sync mode. m: 1->Motor M1, 2->Motor M2, 3->Motor M3.

Peek under the hood

The script below is this module's driver — it teaches the hardware how to respond to the commands listed above. It ships pre-loaded from the factory; most users never need to open it.

On-Module Code

Code that runs directly on this module's MCU. See On-Module Code for an overview.

Script

This example runs using the default DUELink Internal Engine using its Scripting Language, and it expects the module's driver to be loaded first, see the Commands Tab.
