we have been using teensy 3.2 for a few years controlling a bunch of peripherals, including an Xbee on Serial port 2. No problems, more than 20 devices built and hundreds of hours of operation.
Lately we have switched to Teensy 3.5 and after about an hour or so of use RX2 suddenly stops working on the Teensy. Everything else works, including the TX2.
Any clues why the same circuit would work on the Teensy 3.2 and not on the teensy 3.5 ?
We now have about 5 teensys with blown RX2 pins, whats the warranty on Teensys?
