Adafruit Audio FX Sound Board + 2x2W. works for about 30 sec

Post by thefather »

Hello,

So i'm kinda new to adafruit and arduino stuff. i got this audio fx soundboard. and just trying out the demo on it.

I've connected it to a power brick via usb to power it on after copying the sound files.

It works for about 30 seconds. then the green led starts flickering at really low intensity and i get this buzzing sound in sync with the flickering on the speaker output.

Has anybody had this issue or can anybody help me telling me when i'm doing wrong?

Also i might add that if nothing is connected it still does this after roughly 30 seconds.

So turns out it was the power brick it's got some sort of cut off it not enough amps are drawn and it goes into some low power mode and thus underpowers the board.

Phew i thought i had a bad board.

Figured it out thx to this post, which i couldn't find before posting.

Next question would be if anybody knows a power bank that will work with this. cause i have 5 different ones but none of them work.
