This is probably a real noob question. I'm a long time programmer and pretty confident in the logic department but I've always had issues with understanding the electronics fully. I'm getting better at it but still learning. My simple and noobish question is: can I power a second Teensy LC from another Teensy LC that in turn is powered by USB? If so, please show me. I'm guessing utilizing pin 17 in some way. Also of interest might be that is the second Teensy is powering a Neopixel with 30 LEDs (which probably would work fine using 3.3V anyway).
