4.15. NETLIGHT Multiplexing Function
Table 35: NETLIGHT multiplexing function
Pin name Pin number Mode 0(default) Mode 1
NETLIGHT 52 NETLIGHT GPIO31
Note: Multiplexing function need different software supply.
4.16. Operating Status Indication
The pin66 is for operating status indication of the module. The pin output is high when module is powered on,
and output is low when module is powered off.
