Hey everyone... I got it working on my pi! Works great. Here's my quick guide!

Soldering did the trick! I had no idea i2c was so finicky. Thank you very much for clearing that up for me!

Thank you everyone for your help! I'm expecting the address to be 0x18 & I've confirmed that it can use 3.3V or 5v: https://learn.adafruit.com/adafruit-mcp9808-precision-i2c-temperature-sensor-guide/overview Here is what I used to set up my i2c on the Pi: http://www.instructables.com/id/Raspberry-Pi...

Sorry I missed that in your post. The UU appears on the 30 line, and column b.
Thanks!

Thanks for the reply. I just verified I'm using SCL, SDA, grnd and 5v. No change and I'm still getting the UU. Any other suggestions?

I'm only getting a UU when I run i2cdetect -y 1

(I have the proper raspberry pi for the 1)

Could you guys post your pinouts, and anything else you did to get this working such as what you unblacklisted etc..

Thanks!

Was your UBEC able to handle the 47v? I'm looking to do something very similar.

Thanks!
