Hi gang, I've just joined and would appreciate some advice.
I'm not new to electronics (although my experiences are 30+ years old) but I've just started tinkering with Arduino. I have a few sketches under my belt by now, but I needed something smaller than an Uno for a prop build, and a Nano just won't store the sketch (103% - dammit!).
So I've come across and invested in a Teensy 3.6 to do the job. There will be three external boards, all of which are 5v logic and powered. Assuming that I have to run these off a separate buck converter due to the Teensy not having it's own 5v (why is that?), I'm asking the experts here:
Is the Teensy safely 5v tolerant on it's input pins, or am I going to have to use resistors on anything coming in from my external boards?
I don't really want to blow up the Teensy on my first project, not at these prices.
