→Brancher la carte d'extension et mise sous tension
The expansion board can power the WiPy via USB. The WiPy comes with a sticker on top of the RF shield that labels all pins, and this should match the label numbers on the expansion board headers. When plugging it in, the WiPy antenna will end up on top of the SD card connector of the expansion board. A video showing how to do this can be found [[Hack-wipy-generalite#Boot_Modes_et_Safe_boot|here]].

== Guide du la carte d'extension ==
The document explaining the hardware details of the expansion board can be found [https://github.com/wipy/wipy/blob/master/docs/User_manual_exp_board.pdf ici] (''pdf, anglais'').
== Alimentation externe ==
The WiPy can be powered by a battery or other external power source.
{{ambox-stop|text=Be sure to connect the positive lead of the power supply to VIN, and ground to GND. There is no polarity protection on the WiPy so you must be careful when connecting anything to VIN.}}
* When powering via '''VIN''': <font color="red">'''The input voltage must be between 3.6V and 5.5V'''</font>.
* When powering via '''3V3''': <font color="red">'''The input voltage must be exactly 3V3, ripple free and from a supply capable of sourcing at least 300mA of current'''</font>
