Power Warnimg

Ian Morrison All Messages By This Member #2571 I keep getting a low voltage warning even after I changed power supplies and checked the voltage. Is this a YAAC problem or a pi problem.
Andrew P. All Messages By This Member #2572 开云体育 This is a Pi problem. Too much power hogging on too tiny a power connector with lots of I2R voltage drop. Or it could be the peripherals connected to your Pi. Try using a single USB cable from the data (not power) USB-A jacks on your Pi to a powered USB hub, and plug your sound card, etc., into that instead of sucking power from the Pi. Hope that helps.

Jon Adams All Messages By This Member #2573 If you have a dedicated source of 5.1 vdc, try supplying it directly to the header pins on the Pi (pin 2: 5.1 vdc, pin 6: ground). You can abandon the USB connector completely and avoid the plethora of marginal "Raspberry Pi" usb power supplies out there that put out 5 volts at no load and use small gauge wire.
