this 4 pins can be configured
as GPIO pins, and can
change GPIO pin status
through AT command
"Low ( 0 )" effective reset
input.
The reset duration should be
kept more than 300ms
"0"- WIFI connection
available
"1"- No WIFI connection
Can be configured as GPIO.
"0" or "Palmodic Signal" -
Finish module boot up
process;
"1" - Module boot up not
finish.
Can be configured as GPIO.
Module will Restore factory
default configuration after set
this pin "0" more than 1s,
then set "1".
+1.8V Ethernet Data
Interface
Support transformer and
direct connection (AC
couple) mode.
