Hi everyone,
I am using since few years a lot of teensy, and I would like to understand what I can do for the failure I have met now: for teensy 3.6
- When I plug the microUSB power supply, the voltage drops to 4 Volt approximatly and the current reach 0.5A or even 1A. (I do not understand why it could reach so much since there is a 500mA fuse...)
I guess there is either something connected to ground ( I doubt it because I did not touch anything). Maybe the only bad thing I did is that I plug a 5V power supply to Vin at the same time with the microUSB power supply while not cutting the Vusb and Vin pad.
Maybe a component is dead or is dying, My guess if for the LDO.
I can feel overheat at the fuse and the double diode 1A.
Do you have some idea to understand where is the component I could change?
Cheers
