Hello,

I suspect I fried my Teensy 3.6, but I'm not sure. Is there something I can do to verify it?
Looks like the Teensy wont turn on, but the chip itself does not get hot (or even warm).
Hooking the VIN and GND pins to a bench power supply and setting it to 5V and 200ma current limit, the power supply immediately changes to CC mode, so there's probably a short somewhere. The MK66 itself does not get hot or even warm, looking at the board with a thermal camera while it's "shorting" reveals that the only chip that gets hot (~40 C) is this one:

Which according to the schematics I think it's the voltage regulator.
Is there any way to verify that the MK66 itself is dead?

Thanks!
 
You could try applying 3.3 volt power to the 3.3V pin. Some boards with damaged regulators can work with 3.3V external power.
