Adafruit <3 Raspberry Pi - especially how easy it is to hack circuits using the electronics breakout pins! But sadly, the latest official distro "July 15 Raspbian Wheezy" did not have many of the delicious hackables built in. That's why we decided to roll our own distribution. 

Our distro is based on "Wheezy" but comes with hardware SPI, I2C, one wire, and WiFi support for our wifi adapters. It also has some things to make overall hacking easier such sshd on startup (with key generation on first boot) and  Bonjour (so you can simply ssh raspberrypi.local from any computer on the local network)

Like any tweaked distro, this distribution is not designed for beginners! We designed this specifically for what we think hardware hackers want, and may not suit your needs. Please check out raspberrypi.org/downloads for official distributions.
