Wi-Fi and BT

SC66 module provides a shared antenna interface ANT_WIFI/BT for Wi-Fi and Bluetooth (BT) functions.
The interface impedance is 50Ω. External antennas such as PCB antenna, sucker antenna and ceramic
antenna can be connected to the module via these interfaces, so as to achieve Wi-Fi and BT functions. In
addition, SC66-A*, SC66-J*, SC66-E* and SC66-MW* also support ANT_WIFI_MIMO antenna interface
to achieve higher Wi-Fi performance.
