Where To Buy
The Droidalyzer is available from Seeedstudio.com for $67 USD.
IOIOMint is available from Adafruit for $65 USD. IOIOMint is identical to the Droidalyzer with the exception IOIOMint does not include the alcohol sensor.
Both boards can also be used as general purpose IOIO development boards with the added advantage of being portable via the onboard LIPO charger and battery.
