It seems quite curious to me, but I haven’t found anywhere where the WiFi antenna connects. There are two connectors, and I’m not sure if one is for Bluetooth and the other is for WiFi, or if both are part of the same antenna and the other one is for WiFi 5. I think the module have internal antennas and the u.FL connectors are to place an optional antenna, right?
I’m also unable to find any datasheet for the module that includes information about power consumption, voltage requirements, etc.
Thanks!
