There's two of those IPEX connectors. One near the SMA for LoRa and then one further a way.
I'm very hesitant to test it.
The board has Bluetooth, WiFi and LoRa. So it probably isn't LoRa on Second thougth.

Yes I see under my tips at https://gadgeteer.co.za/hamradio/meshtastic-in-south-africa/#htoc-general-tips it mentions another one was for WiFi (on the Lite model anyway). Lifecycle for those PIX connectors is about 30 cycles only.
