I'm looking into making a livestock tracker for our sheep which will consist of a collar and an enclosure small enough not to cause the animal problems, but big enough the house the items mentioned in the title, in addition to a small lipo battery. I also need to be able to fix a tiny solar panel on there to charge the lipo.
On that point, what would be a good way to charge the lipo? Is there a mcu available with this functionality?
My main question here is where I could look for enclosures that would fit this bill.
This is at the very beginning of the idea, so any advice or ideas very welcome.
