Raspberry Pi

The tiny computer everyone loves.

Extra current for the USB ports (B+/2 only)

Raspberry Pi models B+ and 2 are able to supply up to 1.2A over USB using a little trick. This allows us to connect portable hard drives without using powered USB hubs.

Edit /boot/config.txt and add the following:

# extra power for USB ports
max_usb_current=1

Warning

Do this at your own risk. A good power supply giving a stable current of 2A is required.
