[Ovmsdev] External Wifi antenna

[Michael Balzer]

Craig,

that's a very tempting option indeed, if compatible. I'm having no 
issues with Wifi, but the ESP32 V3 is very attractive (no more PSRAM 
issues…).

I don't have the equipment to desolder the module though… or any 
experience with that.

Mark, any info on when the V3 modules will reach our production?

Regards,
Michael
