    I received five units with the LoRa module included however the modules have a shield over them – Does this mean they are the 868mhz version or do the 433mhz also include a shield on the module?

    Hi, add shield for all version, better against noise.

    I now have 10 units will the 433mhz module pre-soldered and will be purchasing more soon. They work well with the RadioHead libraries and have been running for a couple of weeks now on one 18650 li-ion battery – i have removed the power LED and use methods to powerdown the radio and Arduino. I still need to check the power consumption during sleep and will report back. It would be nice if it was possible to monitor the battery voltage similar to the Ada Feathers. Also they run at mhz so program as 8mhz Pro Mini. 🙂

    Hi, yes currently sending version has voltage monitor now from two days ago … on A7 pin.
    But this time missing the charge status LED on the back, probably concern the power use but actually it won’t light up when not charging, we are bad organized and has this missing and imperfect, accept all refunds or review if you are not happy with it. Will add this back as final version soon.
    Have an example code here –

    Looks like a great little board but the documentation (schematic) is not accessible from your link. The schematic that I see online doesn’t show the SPI flash, so it’s not complete.
