Me Stepper Driver

Overview

The Me Stepper Motor Driver module is designed to precisely drive the bipolar stepper motor. When

pulse signals are input into the stepper motor, it rotates step by step. For each pulse signal, it rotates

a certain angle. This module features adjustable drive current and microstepping hardware

adjustment. It can be used in 3D printing, numerical control, Makeblock music robot, precise motion

control, etc. Its red ID means that it should be connected to the port with red ID on Makeblock Orion

by RJ25 wire.

Pin definition

The port of Me Stepper Motor Driver has seven pins, and their functions are as follows:

●

Connecting with RJ25

Since the port of Me Stepper Motor Driver has red ID and the module is motor drive, you need to

connect the port with red ID on Makeblock Orion when using RJ25 port.

Taking Makeblock Orion as example, you can connect it to ports No. 1 and 2 as follows:

●

Connecting with Dupont wire

When the Dupont wire is used to connect the module to the Arduino UNO Baseboard, its pin EN

should be connected to low level, RST and SLP should be connected to high level, STP and DIR

should be connected to digital ports (also can only be connected with STP and DIR pins) as follows:

Guide to programming

●

Arduino programming

If you use Arduino to write a program, the library Makeblock-Library-master should be invoked

to control the Me Stepper Motor Driver. This program serves to make the motor rotating on demand

through Arduino programming. (Input an integer between 0 to 4 on the serial port control tab and

send it out).

●

mBlock programming

Me Stepper Motor Driver supports the mBlock programming environment and its instructions are

introduced as follows:

This is an example on how to use mBlock to control the Me Stepper Motor Driver module. mBlock

can make the stepper motor rotating from lower speed to higher speed again and again.
