So last Thursday (26th Nov 2015) the Raspberry Pi Zero was announced and made available that very day. Basically the Zero is a small and ultra cheap (£4) fully functioning Raspberry Pi, but it doesn’t have any native networking and has only one USB port (which you need an OTG adapter to use).
In the UK I was lucky enough to be able to order two Pi Zero’s and have them delivered the next day. The only problem was I didn’t have an HDMI monitor or a USB hub to connect a keyboard and a WiFi adapter at the same time. My intended use for the Zero’s is for them to be little headless Linux boxes that I can put into various electronic projects and program them over WiFi (Think IoT), so I didn’t want to mess around with HDMI and GUI interfaces.
So here is a little guide showing you how to setup a Raspberry Pi Zero without an HDMI monitor or a keyboard / mouse. We will just use a USB WiFi adapter (connected to the OTG USB port) and a Linux machine to do the setup. If you don’t have a Linux machine available, you could even use another Rasberry Pi with a card reader to set this up.
This should be possible to do on other platforms as well but you will need to be able to mount an Ext4 partition natively.
