Thread: Teensy LC on external 3.3V supply?

    Teensy LC on external 3.3V supply?

    Hey everyone,
    I'm wondering if it's possible to run a Teensy LC off of a separate 3.3V power regulator? I see that it has an onboard regulator that's actually within the microcontroller (never saw that before!). So maybe the only way to power this is with a +5V going to the chip?

    I have a board that already has a very accurate and stable 3.3V regulator so I'd like to use that to power the teensy instead of the on-chip regulator. It matters to me because this is the reference for the DAC.

    Yes, it is. See this thread.
