This is pretty interesting. But rather than add a socket (and move R15 
to R14 to switch from internal to external antenna) I'm tempted to try 
just swapping esp32 modules. Mouser stocks the V3 revision now and the 
ESP32-WROVER-IE comes with the u.fl connector already installed for 
about $3. For $0.29 more I can get 16 MB SPI flash, any reason to not do
