@sundberg84, I've just tried it and that is a better solution than mine for running everything from the LE33. Thanks for taking the time to work that out!

@sundberg84, thanks so much for this board, I bought 10 of them. This has made my sensor projects much easier and they look better too! I think I will get some of the RFM69 version next.
I have a lot of gel lead acid batteries (the 7.2AH type often used in UPSs), and I have been running an earlier prototype off that. I have now just changed over to your board and this is how I modified it to work the way I wanted:
This enabled me to run the board off 12V, keep an eye on the battery voltage, and run the rest from the LE33 regulator. It seems to be managing so far, with 3 x DS18B20 temperature sensors. I'm monitoring the fridge outside, inside and freezer temperatures with this module.
