TP1
I/O
GPIO2, used for query of the module
printing information
TP2
I/O
GPIO0, used for the module production test
TP3
RST
Hardware reset pin, which cannot clear the
Wi-Fi network configuration
TP4
UART0_
TXD
User-side serial interface, which generates
information for the module production test
when the module is powered on and starts
TP5
UART0_
RXD
User-side serial interface, which generates
information for the module production test
when the module is powered on and starts
Note:
1. Test pins are not recommended.
2. RST is only a hardware reset pin and cannot clear the Wi-Fi network configuration.
3. UART0 is a user-side serial interface, which generates information when the module is
powered on and starts.
