connect ESP32-S3-WROOM-1U Antenna

[tonbor]

I bought ESP32-S3-WROOM-1U to use with an external antenna. But is the internal antenna connected or the ipex connected?

If I'm looking at the right module, there cannot be an internal antenna under the shield, so it's safe to assume the IPEX connector is the only way to get the signal into the module, as there is no PCB antenna trace on it.
