{{PiFace2-Manuel-NAV}}
{{traduction}}
PiFace Digital 2 requires 3.3V to supply the integrated circuit (which requires negligible current), which it always takes from the Raspberry Pi®. The relays and LEDs require 5V to
operate.
PiFace Digital 2’s 5V can be configured to be supplied (as detailed below in Jumper settings)
* Independently from the Raspberry Pi® via the power screw terminals
* From the Raspberry Pi’s 5V
* Via the power screw terminals, and used to power the Raspberry Pi
{{ambox-stop|text=Warning: Never have separate power supplies for both the Raspberry Pi and PiFace Digital 2, when the power jumper is connected.}}
{{ambox|text=Note: As discussed in the Output ports section PiFace Digital 2 does not supply power on its open-collector output pins or relay contacts!}}
The top 3 set of terminals on the right of the board is used to supply or take power, with the top pin being 5V and bottom two ground. In many applications these do not need to be connected to anything, as the PiFace Digital 2 will be powered by the Raspberry Pi
