matrix portal m4 smoked

by funnymonkey on Sat May 01, 2021 4:40 pm

I was just trying to get the board programed and it smoke started coming from one of the chips it wasn't even attached to the led display yet. the smoke was coming from where the red circle is. i got the 64x64 RGB LED Matrix - 2.5mm Pitch - 1/32 Scan PID: 3649 so i soldered the E pad to 8. the E was never connected to 16 i mad sure with a magnifier glass

Does anyone know why smoke would come from this spot? It seemed to come from underneath it.

That would be a component failure of some kind, but smoking a chip usually takes a lot of current.

What kind of power did you have connected to the matrix when the chip failed?

Just a usb c cable connected to my computer. I haven't had any problems with the other one I ordered from you after.

USB-C can deliver enough power to smoke a chip, thanks.

Given the location, this sounds like an early component failure. Send a note containing a link to this page and your order number to support@adafruit.com. The folks there will get you a replacement.
