(*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. 2.3Test PinDefinition Table 2 shows the generaltest pindefinition of TYWE3L Table 2.

TYWE3L DATASHEET 5. Antenna Information5.1 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.
