What type of IPEX antennas are required for the new ESP32-S2-SOLO-2U and ESP32-S2-MINI-2U modules?
Thanks!

I want to know too. This document only says IPEX antenna. But IPEX antennas have many variants. I think it will be helpful if this list is updated with the exact types.

Agreed. I also emailed requesting the latest datasheet but haven't heard back yet. I'll respond here if I found out, but hopefully Espressif can let us know.

I received the datasheets, and the antenna types are the same as the previous generation.
Btw, I'm curious as to why Espressif chose a type III IPEX connector for the mini. It makes the module unfeasible for me (and I assume others), because the connector is rare and makes the antenna too expensive and difficult to source.
