Following on from the last post  which was about the process and building, this is just an overview of the latest design. The kicad project files along with the schematic , layout , and BOM can all be found on github . The future Firstly, and I think I've expressed these comments before - but I'm still absolutely dumbfounded that the software and facilities are available for a basic hobbyist to be able to design and create something like this now. Yes it wasn't simple and took a while, but still, a few years ago this would have been impossible/unthinkable. New new design This is the new design. I spent some more time tidying up and redesigned the charger module again since the original one was too basic/primitive. The new new There are quite a few changes and improvements on this new design.  USB connection I changed to a USB-C connector, and the USB connection can be switched between the NRF and BG96 chips, most of the time the NRF will be useful but if you need/want to d...

How hard could it be? 🤷 Evolution Version 0 For version zero of the tracker I tried using off the shelf 'personal tracking' devices, this proved that it was possible to build my own tracking site. Initially I thought I really didn't want to spend any time trying to build my own device, but inevitably concluded that was the solution. Version 1 The first incarnation of the custom tracker was the klutzy A9G based system  - well it wasn't klutzy at first, but after several iterations and enhancements it ended up that way. The A9G was incredibly cheap and worked reasonably well, but the module has some major design flaws and it can't do bluetooth (hence the klutzing). Version 2 The second version switched to using the RAK5010 based board , again it started elegant and ended up with multiple impr...
