Overview
The LV8702VSLDGEVB is an ON Semiconductor motor driver
module featuring the LV8702V. This module is capable of easily
driving a stepper motor.
Motor driving is made easy with Arduino Micro
The LV8702VSLDGEVB comes with a Baseboard for facilitated
plug−and−play connectivity with an Arduino Micro.
GUI and Open−source API Functions are available for custom,
user−specific motor driving programs.

Rotation of the Motor is Controlled by a Single Pulse Signal, which
is Advantageous for Smooth Driving (Micro−step) and Rotating
at High Speed Rotation
4 Patterns can be Set for Full, Half (2 Patterns) and Quarter Step
High−efficiency Drive that Adjusts the Current to the Optimum
Current according to the Motor Load and Rotational Speed
(in Half, Quarter Step Setting)
The Reduction of Power Consumption, Heat Generation,
Vibration and Noise is Achieved
User−friendly GUI Allows Operation Check and Sample Program

Stress exceeding this voltage or current may risk damage to the device. Functionality and reliability may be hindered if the device exceeds
these values. The maximum current value, IOmax, does not guarantee the module can handle that much current. If the device overheats,
thermal shutdown will occur.
