Very happy to have just received the PCBs for the next iteration of this temperature logger, the NestProbe TL2.

In an effort to reduce cost and complexity, I spent much of past autumn designing a new model of the temperature logger. Thanks to Jan who pointed out details about sensor accuracy, I also changed the temperature sensor to Silicon Labs' Si7051, which is more expensive but more accurate and NIST-traceable.

Main changes for this iteration are:

I'm looking forward to put this on the frying pan and start coding!
