Re: [DIYbio] Microcontrollers

I've found that simply using a powered 4 port hub to power my RPi and plugging

its input into one of the RPi's outputs gives me three high power ports and one
port left over on the RPi.

Why people worry about adding a hub is not really clear to me. You'll need power
anyway, and the extra ports are really handy.

Here's a great overview of the issues with the limited 5V power supply on the RPi, and ways to bypass it:

Good guess.  It's against the USB spec to draw more than so much.
The wire allows more, so meltdowns of supplying USB hosts or hubs could ensue.
