• Watch batteries have no hope of powering the cellular module. You need to use Lithium Ion batteries. Unfortunately the RAK8212 has a poor voltage regulator that draws more current than the cellular module in sleep, so this module is a poor choice for something that has to run for a long time.

    As for waterproof cases, there's many suppliers of IP rated enclosures.

  • Hi,

    Thank you very much for getting back to me. Given your reply I have decided this is not the tool for the job I have.

    Much appreciated.
