Hello,

Are there a list of approved external antennas for ESP32-C3-MINI-1U?

Also, if anyone has any expertise or experience with FCC 15B compliance testing for low power devices using external antennas (ie. not precertified modules), I would appreciate any information on what additional testing is entailed as opposed to using pre-cert modules.
