Why in the world would anyone set analog in voltages as 1.8V??? Everything I have and know about uses 0-5V. I freely admit I am a complete newbie at the BeagleBone Black (BBB), but come ON. I have an unverified theory that circuitry in the processor chip is unable to handle 5V in, but couldn't they have used a wider trace or something? I purchased 2 BBB's to use on for monitoring engine temps (4), 3D positioning, G-forces experienced, and airspeeds. All my A/D chips output 0-5V while only a couple support I2C. I was all excited about the BBB until I actually spent nearly $300 only to find out it's major limitation. I assumed EVERYONE in the embedded world worked on 5V analog in, like Arduino and Raspberry Pi. Does the Arduino have I2C? Lots of reading seems to indicate, also, that not many versions of Linux or Android for BBB support graphics acceleration in hardware that is available in the BBB. <sigh>
