  • On the back board diagram the ‘interior’ pins (next to the microsd slot but not along the two long flanks) are shown and one is labelled ‘VBatt’ with the subheading that it’s for a 3V coin cell for the RTC. The board itself seems to also have a small ‘VB’ label in the silkscreen but the diagram resolutions isn’t stellar. https://cdn.sparkfun.com/datasheets/Dev/Arduino/Boards/teensy35_back.pdf

    EDIT: lost track of brain before posting, this forum post over at PJRC also clarifies crystal is built in, and you can make out what looks to be 2 crystals by the reset button. “RTC crystal: The crystal for the RTC is part of the Teensy 3.5/3.6, while on the Teensy 3.2 you have to solder an external crystal.” https://forum.pjrc.com/threads/36613-Why-Teensy-3-5-or-3-6

  • The video mentions using the ‘octows2812’ library. From what I’ve been able to find on PJRC website/forums/rest of the interent, the octows2811 library currently doesn’t explicitly support the teensy 3.5/6 but I’d love to be proven wrong. I’ve been waiting with bated breath for the octo library to come to the newest teensy’s. Any chance Nick (or anyone) could post up a link to the library used in the video and maybe even the code for running the animation shown in the video?

  • Thanks for the link to your project. As cool as the whole GPS box saga has been, the tidbit that was most useful was noting how the OFF pin works. Being Aerospace and not EE (and hence looking at the components and traces wasn’t going to give me any hints) it was nice that you spelled out the following in plain english:
    “When the sketch decides it?s time to shut down … it simply brings the Pololu?s power control pin high, cutting power."
    Not that with some tinkering I couldn’t have figured things out, but now I know. Cheers mate!

No public wish lists :(
