-If you're running off of a battery, chances are you wanna know what the voltage is at! That way you can tell when the battery needs recharging. Lipoly batteries are 'maxed out' at 4.2V and stick around 3.7V for much of the battery life, then slowly sink down to 3.2V or so before the protection circuitry cuts it off. By measuring the voltage you can quickly tell when you're heading below 3.7V
+Si vous alimentez votre projet depuis l'accu, il est fort probable que vous désiriez connaître la tension de l'accu! De cette façon il est possible d'avertir l'utilisateur qu'il est temps de recharger l'accu (en branchant le montage en USB). La tension max de l'accu Lipoly est de 4.2V (juste en sortie de charge) et à 3.7V durant la plus grande partie de la durée de vie de l'accu, puis la tension diminue lentement jusqu'à environ 3.2V (juste avant l'activation du circuit de protection).
-To make this easy we stuck a double-100K resistor divider on the '''BAT''' pin, and connected it to '''D9''' (a.k.a analog #7 '''A7'''). You can read this pin's voltage, then double it, to get the battery voltage.

-You have a lot of power supply options here! We bring out the '''BAT''' pin, which is tied to the lipoly JST connector, as well as '''USB '''which is the +5V from USB if connected.

While you can get 500mA from it, you can't do it continuously from 5V as it will overheat the regulator. It's fine for, say, powering an ESP8266 WiFi chip or XBee radio though, since the current draw is 'spikey' & sporadic.

-We wanted to make the Feather easy to power both when connected to a computer as well as via battery. There's '''two ways to power''' a Feather. You can connect with a MicroUSB cable (just plug into the jack) and the Feather will regulate the 5V USB down to 3.3V. You can also connect a 4.2/3.7V Lithium Polymer (Lipo/Lipoly) or Lithium Ion (LiIon) battery to the JST jack. This will let the Feather run on a rechargable battery. '''When the USB power is powered, it will automatically switch over to USB for power, as well as start charging the battery (if attached) at 100mA. '''This happens 'hotswap' style so you can always keep the Lipoly connected as a 'backup' power that will only get used when USB power is lost.
+Adafruit à conçu le Feather pour qu'il soit facile à alimenter qu'il soit branché sur un ordinateur ou sur un accumulateur. Il y a '''deux façon d'alimenter''' le Feather. Vous pouvez connecter un câble micro-USB (sur le connecteur micro USB) et le Feather utilisateur la tension USB 5V pour la l'abaisser à 3.3V. Vous pouvez également brancher un accu Lithium Polymère 4.2/3.7V  (Lipo/Lipoly) ou accu Lithium Ion (LiIon) sur le connecteur JST. Cela permettra au Feather de fonctionner depuis un accumulateur (''pile'') rechargeable. '''lorsqu'il est alimenté via USB, le Feather passera automatiquement sur l'alimentation USB et commencera à recharger l'accu (s'il est branché) avec un débit de 100mA. '''Cela s'effectue comme 'hotswap' (passage à chaud) d'une source d'alimentation à l'autre''' permettant à l'accumulateur Lipoly d'agir comme une alimentation de secours lors de la perte d'alimentation USB.

−	The '''Feather M0 Express''' uses the extra space left over to add a '''Mini NeoPixel''', '''2 MB SPI Flash '''storage and a little prototyping space. You can use the SPI Flash storage like a very tiny hard drive. When used in Circuit Python, the 2 MB flash acts as storage for all your scripts, libraries and files. When used in Arduino, you can read/write files to it, like a little datalogger or SD card, and then with our helper program, access the files over USB.
