    Is level shifter needed for using Teensy on 5v driver

    in General Discussion

    Hi, everyone and Chris,


    I am working on assembling the ar3.

    I am a little confused.

    Based on the manual, It seems that Teensy is used to energize the 5v driver directly. Does it cause to miss the step?

    Or, do you have any level shifter to introduce for this high frequency?


    Thank you for any suggestion!

    The Stepperonline drivers operate with no issues at 3.3v. They were supposed to be updating the driver manuals but it hasn't been done yet.
