Last night I ‘let the smoke out’ on my Teensy 3.0.
Turns out that jumping the +5 and GND with a filter capacitor fried the chip. I’ll have to be more careful when measuring with the oscilloscope.
You can see the tiny smoke hole in the top of the chip.
Ouch. But also, WTF? Power decoupling shouldn’t do this. And lastly, if you want to venture into repairing it: http://www.mouser.com/ProductDetail/Freescale-Semiconductor/MK20DX128VLH5/?qs=sGAEpiMZZMuyGAGFEBEmZjXo3smxnGyK However, you’ll have to settle for the LUFA version of the Teensy HID as a bootloader, as the HalfKay one is proprietary from PJRC.
We need a -1
There must have been a short. Decoupling doesn’t do this and you have to decouple.
I guess I wasn’t clear. Yes I did short the power. I’m guessing that the filter cap made it worse discharging more power.
Myah, I’ve done dumb things like that. Fried one of my custom charger boards recently … VCC alligator clip scraped some of the mask and exposed the ground plane to which it gladly formed a bond, sending an $11 IC flying, quite literally.
