Specification Parameters

Female Interface Subinterface	Hardware pin definition (PIN)			Description
	PA	PB	PC
VIN+	6	6		DC5V--15V, the input voltage ripple is required to be less than 100mV, otherwise it will affect the WiFi transmission performance
GND	5	5	8、4	Module ground
LAN	1:RX+ 2:RX- 3:TX- 4:TX+	1:RX+ 2:RX- 3:TX- 4:TX+		PA and PB are parallel interfaces, but they are actually the same port (only one can be used at a time)
LAN Port Status Indication Output			3	1. MOS tube open circuit output, built-in 330Ω current limiting resistor 2. Output current: 10mA
WAN Port Status Indication Output			2	1. MOS tube open circuit output, built-in 330Ω current limiting resistor 2. Output current: 10mA
WiFi Status Indication Output			1	1. MOS tube open circuit output, built-in 330Ω current limiting resistor 2. Output current: 10mA
Reset Signal Input			5	After the module works normally, keep the low level for more than 3 seconds, the module will restore the factory parameters (less than 0.6V is the low level)
UART-TX			6	TX signal line of UART used for serial port transparent transmission, TTL level output
UART-RX			7	RX signal line of UART used for serial port transparent transmission, TTL level input
Power enable pin			0	Module power enable control pin, the default state is power enable. If the control voltage of this pin is less than 1V, the module power supply is off
