Hi,

I was trying to use a 3.7V LiPo battery with a voltage boost to 5V to power Arduino yun, and a PNP transistor 2N2907A in the middle as a switch. I tried this circuit on Uno and it works, but when I put this power on Yun, the USB led on Yun's board keeps blinking and apparently it doesnt work.

I also tried to directly power yun from the power boost and it works, so I guess it is because of the transistor. Could anyone give me some help here?

Thanks!
