Is there a schematic, component layout ETC for the Teensy 4? I've a problem with mine. Was running one of the ILI9341_T3 graphics example sketches overnight which was working fine, but when I checked on it about 18 hours or so later, it was dead. The 3.3V pin is reading about 0.8V or so. Measuring the resistance from the 3.3V pin to ground shows the fault: 14.2 Ω. A schematic would be helpful, but I'm afraid it's toast. Ran good for 3 days. Live fast, die fast I guess. I was really getting attached to the little guy....
Measured voltages with only USB plugged into Teensy:
Curious about where VBat and On/Off pins are getting those voltages from.

Measured voltages with only USB plugged into Teensy:
PIN | Voltage |
VBat | 2.3v |
3.3V | 0.80v |
On/Off | 2.3v |
Vin | 5.0v |
