[RaspberryPi]: Notes from the fields

Men may come and men may go…..but Pi goes on for ever.

— George Augustus Sala

One of my 2015 Christmas gifts is a Raspberry Pi 2 Model B v1.1.
Thank you Santa Claus from Australia!

Take a quick look at the specification:

• 100 Base Ethernet
• 4 USB ports
• 40 GPIO pins
• Full HDMI port
• Combined 3.5mm audio jack and composite video
• Camera interface (CSI)
• Display interface (DSI)
• Micro SD card slot
• VideoCore IV 3D graphics core

After about one hour reading documentation, downloading and installing NOOBS and then RASPIAN, I can ssh to it from my laptop with default login (pi) and password (raspberry).

Updated 31-08-2018: Download and burn Raspian Stretch to SD Card. Follow this simple awesome guide to create an empty file named ssh at the root to enable ssh so we can connect via ssh for the first time.
