My 2 week old teensy was working before, however, often when i did a reset the small red led came on and nothing happened. The uploaded sketch would not run.
But after disconnecting the power and plugging it in again, it would work.
Tonight this happened again, but when i plugged it back in...... Nothing!
No led, No small red led. No running sketch!
After connecting it to USB (usually use it with the VIN) it wouldn't work either. So i took my multimeter and measured the VIN pin which gave me 5V.
Then i measured the 3V pin (almost next to the VIN pin) and it gave me 0.48V. So i measured the other 3.3V pin and it gave me 0V.
I measured the pins of the voltage regulator on the teensy and only one pin gave me 2.68V
So i think i have a faulty regulator. Am i right?
I have been very cautious not to overpower/over-voltage the teensy with external power. I never used USB AND external power together.
It seems not to be my fault so can i apply for a replacement?
