5.1V 0.7A :shock:

That's not even close to enough power for a Pi 3B (it's barely enough for a Pi Zero)!

And as fruitoftheloom said, chargers are not power supplies. Things should work much better with the official power supply.
Actually... That's the current spec for the original Model B!

Re: Use official display with Power over Ethernet hat

Output from one of the Pis USB ports to the microUSB power input on the display should do it.

I realize this will look like nitpicking, but one really needs to describe any given Pi correctly. As already noted, the Pi Model A+ (aka A+ or Pi1A+) does not have on-board WiFi.

So I have to use a Power Supply Like 12v and 5A or Something and divide it for both Raspi and Arduino. Like in 5V - 2.5 A. and supply them Both.
Do not try to use a 12v supply directly to a Pi. You will destroy it.

Re: USB hub chip compatibility

It occurs to me.... The newly release RPF keyboard contains a USB hub. The OP might get one a check to see what chip it uses as one might suspect that the RPT would be certain to use one that is absolutely compatible with Pis.

Also is it necessary for it to be powered? I've heard of people using unpowered ones, I don't know if you can change the config files to increase power to the USB port on boot.
The max power option went away some time ago. 1.2A is now standard for Pi2B onwards.

Re: Booting from SSD

Only the 3B with the OTP bit set, & the 3B+, (3A+ also), will boot directly from USB. (Previous models need a card with some boot files on it.) Almost, but not quite... You can set the OTP bit for USB MSD booting on a Pi2Bv1.2 as it uses the same SoC as the Pi3B. Then there are the Cm3L and CM3L+.....

As a USB device it *shouldn't* draw more than 500mA.
