Sadly I killed my first Teensy today.

I have been using teensy's since 2015 but never killed one before.

Now while working on a GPS logger I accidently touched the SCLK (13) with the positive pole of a
freshly charged LION cell. Just for a very short moment.

I realized what happened and checked straight away if the Teensy 4.0 was still working.

And it was! I could still see the messages coming in from the Adafruit Ultimate GPS on Serial1.

So I continued with connecting a 2.9" e-paper on SPI.

Sadly, after this it never worked again, Known good display, no shorts at the pins.

awel, I have to use one of my backup's now, Teensy 3.2 or 3.5 or 3.6

For all of you out there, don't do the same!

Regards, Otto
