This will be a groundside TX version of the ELRS Redundant Diversity RX
ToDo:
Come up w/key features and Modify the schematic by Nolan Haines for groundside TX applications
Create a corresponding layout
Ideas
something like Xrossband would be pretty cool. It's the next step after Gemini in terms of TX. Basically have two Geminis on the board, with one at 900-910 MHZ and the other at 2.4-2.44GHz. https://fpvguru.in/blogs/expresslrs-gemini-xrossband-the-future-of-dual-band-fpv-control/ . Hardware wise it could use the same LR221s, main differences would be in firmware
Some side research

ENIG has more losses than bare copper for coplanar waveguides

Note: the main point of a ground pour is manufacturability and shielding, but it may not be desirable everywhere if we want a microstrip configuration instead of waveguide
