Troubleshooting

howdy team!

i sadly overloaded or reverse polarity’d more poor pico. i see a blown component on the board which im guessing is the power regulator? it has 3 leads on one side and 2 on the other. i have a hot air solder station, so i was thinking i could try and replace it. anyone know what this component is so i could get some and try my luck replacing it? a buck for a component and some squinty soldering sure beats junking an otherwise good $30 board eh?? grateful if anyone could share such knowledge!

cheers!

You can do a quick test to see if it’s worth replacing.

If you remove the voltage regulator ic, and power 3.3v directly to the 3v pad on the underside, the PB should work unless the main chip was also damaged.

It’s an AP2112K-3.3TRG1 or equivalent.
