4 Wi-Fi and BT
SC66 module provides two shared antenna interface ANT_WIFI/BT and ANT_WIFI_MIMO for Wi-Fi and
Bluetooth (BT) functions(SC66-CE and SC66-W just support ANT_WIFI/BT). The interface impedance is
50Ω. External antennas such as PCB antenna, sucker antenna and ceramic antenna can be connected to
the module via the interface, so as to achieve Wi-Fi and BT functions.
