I having an issue with my Pi crickit hat and I'm not getting a whole lot of help on Adafruits forum. I'm getting an almost constant undervolt warning on my monitor, when powered via the crickits barrel connector. And thats with the recomended 5V 4A power supply I bought from them a while back. If I power the Pi via its power port with the official Pi supply no undervolt warning. The product page for the crickit says not to power it that way though? It advises to only use the crickits power port. I get 5.1 V out of the supply with no load. And 5.09 at the crickits barrel jack contacts with it running. I'm only seeing 4.75 V on the GPIO 5V pin though and it must be dipping even lower. As soon as I open a browser or do anything the lightning bolt flashes on screen.
The led next to the yellow caution triangle on the board is on too? Although the product page says its supposed to be Red, and not a good thing if it is lit up? Its even lit during thier youtub video on the crickit hat. I have yet to see the green smiley face LED to ever light up. I tried three different supplies and same deal with all of them.

Look where the power cable is plugged in and you will see a smiley face and a triangle. The LED next to the caution triangle is on? I would think it should be the other one that should be on? I can't actually tell if its yellow or green? My partial color blindness makes that hard. Maybe they have them backwards or something because I think the smiley face one lits up red during the video?
