The moment…
+ Do it yourself
+ Open-source hardware and software
+ Entrepreneurship / Crowdfunding
+ Creativity
+ Cheaper Tiny Computer
+ Easy of Embedded Development

#DV13-#iothackfest

Starting your Pi

• Download your choise of OS:
• Raspbian (most popular and used here)
• Pidora
• Archlinux
• RISC Os
• Media Server XBMC
#DV13-#iothackfest

@java

Image to Card

• Linux Command
• dd if=<img.img> of=/dev/sdb
• Take CARE!

#DV13-#iothackfest

@java

Power Supply

• 5volts 1amp recommended!
• Micro USB
• Use a good power supply, it's sensible
• Rebooting use to be a power supply problem
• UBEC for battery regulator

Raspberry Pi GPIO

• where the fun lives!
• 17 digital pins:

• 7 general, 1 pwm, 2 I2C, 5 SPI, 2 UART

• CMOS (3.3 volts) and not TTL (5 volts) take care!
• MAX232 can convert 5 – 3 volts vice-versa
