Refreshed things a bit to improve clarity, make installation easier, and to reduce costs when manufacturing in bulk. There is no reason to upgrade already installed modules to this revision.
* Changed the module to be installed on the back of the PCB again as it is much easier to install that way.
* Added pad for the STAT pin. There's no real use for this at the moment.
* Changed the layout slightly to allow room for all of the capacitors' legends. This should make things more clear when assembling a module by hand.
* Changed the legends for the jumper pads to use the net name instead of the designator. This should make things easier during installation.
* Added legends to specify 3.3V/5V for the pads that connect to the power switch footprint. Hopefully, this helps keep people from installing the module incorrectly.
* Updated the TPS2113 footprint to the new one that allows using either the TSSOP or SON package. This should give more flexibility regarding part availability.
* Changed part numbers to more readily available parts. This should reduce the cost of machine assembly.
* Migrated files to KiCad 7
* Added RTC
* IC: Analog Devices Inc. DS3231MZ
* Battery holder (CR1616): Keystone Electronics 3012
* Cleaned up traces
* Changed ground fill to solid
* Removed test pads and LCD solder jumper
* Cleaned up/prettified silkscreen and logo
* Cleaned up some footprints (more to come eventually)
* Added 3D models for board display
* Schematic image is now a PDF since it has 2 pages
