Présentation
Nous arrivons bientôt au mois de Décembre, les fêtes et Noel ne sont plus très loin et qu'apprenons nous? ... Un nouveau Pi est né, longue vie au Pi.
'Le Pi Zero est le plus petit, plus fin et plus abordable Pi jamais créé. Tellement bon marché qu'il à été distribué avec chaque exemplaire #40 du magazine The MagPi.
Quoi de neuf? Quelle différence?
Wow a new Pi - so exciting! The Pi Zero is the smallest, most affordable Pi ever. Wonder what's new & different? Let's check it out!

La taille
First up, the Pi Zero is small and thin
65mm long x 30mm wide x 5mm thick
(31mm if you include the little sticky-out bits of the microUSB jacks)
Way smaller than the Pi 2 or B+ and even smaller than the A+, its 60% the size of the A+: same length, and about half the width:

And about 40% the size of the Pi 2 or B+

Processeur et vitesse
To keep the Pi Zero low cost, the processor and RAM are kept pretty basic. Instead of the Pi 2's zippy quad core ARM v7, we're back to a single-core 1GHz ARM (same processor in the Pi Model B+ and A+). We also have 512 MB of RAM with a 'package-on-package' setup. The chip shown here:

Is the RAM that is sitting on top of the main processor.
For maker and hacker projects, this isn't a big deal. You're essentially going to get the same performance as the Pi A+ or B+. If you're looking for something that can do some more serious processing, check out the Raspberry Pi 2.
Connecteur carte Micro SD
Not much has changed here, we're still going with MicroSD for size and ease of use (they're the most common card size these days!) This time the card holder is up top and is push-pull style not push-push. Honestly, I prefer it this way since you wont accidentally 'push-pop' the card out.

Sortie Vidéo
HDMI Video is still available, you'll to use aMini to Standard HDMI adapter to connect an HDMI cable. There's no 3.5mm jack with composite out, however you can get PAL or NTSC out via two 0.1" pads. We've got a bigger writeup here about Pi Zero video outputs.

Sortie Audio
No analog audio out, but if you connect HDMI to a monitor with speakers you will get HDMI digital audio. It's also possible to hack analog audio out with a few passive components, see our more detailed look at Pi Zero audio output options.
Port USB
Like the Pi Model A+, the Pi Zero does not have a USB Hub built in which means you get one USB port! Moreover that USB port is not a standard type A port, instead it is a 'USB On-The-Go' port

In order to connect a USB device (mouse, keyboard, WiFi) etc you'll need a USB OTG micro B to A cable:
If you need to connect multiple USB devices, a simple USB hub will do what you need. A powered hub is even better, and will let you power high-current USB devices like WiFi adapters and even external USB hard-drives.
As a bonus you can power the Pi Zero from the hub (the power cable does not pass any data) - just plug the power micro USB cable into one of the ports.
