Re: Increasing USB current on Pi 3B+

The hub arrived this morning and having connected everything up, with the Pi, hub and HDDs all powered by my 5v 5A power supply, everything works as it should. Data can be copied from one HDD to the other without trouble and there's no chirping from the drives any more. Except that for reasons I can...

Re: Increasing USB current on Pi 3B+

oh...do note that some USB3.0 hubs does not work well with the RPi if you can still get a USB2.0 hub, the better. I believe there are still some in the wild.... The one I ordered was a NewLink and it's USB2.0. ModMyPi list it but it was out of stock. I found one on Amazon Marketplace, then just aft...

Re: Increasing USB current on Pi 3B+

Also note that Seagate drives are power pigs. While I don't recommend running more than a single USB powered HDD from a Pi, there are other brands that are much more frugal on power. Interesting. The drive spec says current consumption is 100mA but it turns out that is quiescent, if you try reading...

Re: Increasing USB current on Pi 3B+

Thanks for the replies, I have ordered a powered hub which should work with my existing power supply. Whileit's an extra lump of hardware it doesn't risk damaging the Pi. I'll just need a bigger case!

Re: Increasing USB current on Pi 3B+

Thanks - I have checked the voltage at the GPIO power pins and it's 5.1V. I tried applying power to those pins to bypass the fuse but that makes no difference. If I plug both drives into my PC they work perfectly. Is it possible to disconnect the USB sockets' +5V pins and wire them direct to the pow...

Increasing USB current on Pi 3B+

I know the subject of increasing the power available from the USB sockets has been covered at length on the forums but I can't find anything specifically for the Pi 3B+. I am building a basic NAS using a 3B+ and two Seagate 1TEAP5-500 1TB USB hard drives, powered from a 5V 5A power supply. Seagate s...

Re: STICKY: Introduce yourself!

Hi everyone, Richard here. I've been dabbling with RPis for a year or so with varying degrees of success! I've got a RPi3 in the living room running moOde audio, and last year I built a project for the local museum which plays a WAV file and controls a smoke generator, based on a Pi Zero W. Getting ...
