(*1) This pin can only be used as ADC input, cannot use it as normal I/O. when not using,

just connect nothing. When used as ADC input, the input voltage range is 0~1.0V.

(*2) UART0 is serial port, during power on progress; this serial port will output something,

which can be ignored.

5. Antenna Information

5.1 Antenna Type

Antenna can be connected only using On-board PCB antenna.

5.2 Reduce Antenna Interference

While using the On-board PCBantenna, in order to have the best Wi-Fi performance, it’s

recommended to keep a minimum15mm distance between the antenna part and the other metal

pieces.

User’s own PCBA design is recommended NOT to pass any wire, NOT do copper pour under

the region of the module’s antenna, to avoid interferences.
