Wi-Fi and BT

SC650T 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 the interface, so as to achieve Wi-Fi and BT
functions.
