  • While the micro on the Teensy LC has some RTC hardware it is missing the capability to use an external crystal and as such at least at Mar2015 the linked ‘using RTC’ page was not relevant and the software not supported. Suggest removing the link in the interest of avoiding confusion

  • Just a thought having looked at the schematic, the design assumes sane output selection. While I love the concept here of getting a class straight into Arduino without having slow everybody down while you double and triple check all the wiring there are no limiting resistors on the pins intended as inputs so you can still set pinmode, press the switch and break a $70 board

    While a big fan of learning by letting the smoke out I normally only stand back and watch when it’s single LEDS and such that get binned afterwards.

    I’m voting for the addition of a smattering of 125 ohm resistors on the next revision for a slightly less fraught class room experience.

No public wish lists :(
