Some info for those in need of a better Wifi signal than achievable with the builtin ESP32-WROVER antenna:
A friend of mine on the german Twizy forum had severe signal issues, using an external router antenna he saw an improvement of ~10 dB.
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 that? Craig
