I finally got my LAST version to work with my projects, and now to see WHAT ELSE the arduino devs have changed!
The last sentence of the first paragraph in this product description makes no mention that YOU MUST HAVE a supported arduino version to install - valid versions, 1.0.6, 1.6.5-r5, 1.6.9, 1.6.11 or 1.6.12.
Any other version, and you're out of luck.<p>I know that the RTFM/command-line junkies among us will say that there is an encyclopaedia called PJRC that I should read. To that I say, NO! The vendor SHOULD have made this note.</p><p>Oh, you have to DL a compatible arduino version, install and RUN ONCE, then terminate arduino before installing.</p></p>

Unless you actually use the 3 pads or use one of the third party shields that had a pogo pin to bring out the reset pad to a pin, it should not present a compatibility problem.<p>RobBrownNZ, you might ask the same question at the forums at pjrc.com, which are the development forums for the Teensies.</p></p>
RobBrownNZ on DEV-13736 - Teensy 3.2RobBrownNZurn:uuid:2d714cc0-d679-a27d-9dd5-e8b513499d662015-09-25T22:13:51-06:00<p>I tried Teensy 3.1, and found that it didn't reset reliably when it was powered straight from 3.3V (rather than from USB). Adding a capacitor on the reset pin helped but it still wasn't 100%, and then I accidentally ripped the 'R' pad off the PCB and gave up on the board as a result.
Has anyone else experienced unreliable resetting with these things? Any advice on how to improve it?</p>

(Version 3.1 used the regulator that is built into the microcontroller.) They are otherwise identical, so there should be no compatibility issues if you are putting these into something designed for version 3.1.</p>
