The confusing part is that we ran both of these boards for testing and logged data using the Teensy on many occasions and had absolutely no issues. Fast forward a couple months and within a couple weeks, we had three Teensy's fail in the same way and nothing was altered from the previous system...

The Teensy Vin is connected to a switch that allows us to disconnect it from the regulated power source instead of having to unplug the micro. The speedometer has never been connected to the board and that circuitry is just intended to act as a connection point for a Qwiic 14-segment display to...

The 11.2V is not on the brake light board, it is on the other PCB. The voltage is coming in from a lipo and is immediately connected to a fuse into a 5V lin-reg upon being plugged into the board. Nothing on the actual pcb is running higher than 5V other than the two regulators being powered at...

It's the input signal from an inductive proximity sensor with a voltage divider resistor setup within the wire harness to regulate from 11.2V to 3.3V

Could someone take a look through my schematics and see if there is anything obvious that might be killing my Teensy 4.1s?

Our other board that also uses a Teensy is this one that has the input of engine rpm and a sensor to detect rotation for rpm of a shaft. The first board (Rev1) used a hall effect sensor powered at 3.3V with two magnets in the collar. The second board (Rev2) used an inductive proximity sensor...

Here is one of our schematics for the Teensy. This board operates a brake light when the current through our pressure sensors changes on brake lines.

I've been using Teensy 4.1s for data acquisition systems and have 4 that have now reached a point where they output 0.6V on the 3.3V pin even though the 5V pin is measuring accurately. I have powered with both a usb cable and 5V regulated from 11.1V and 14.8V lipos using different lin-regs on...
