CX-WIFI-2NET module is an all-in-one 802.11 b/g/n Wi-Fi and Ethernet module that 
provides a way to connect a user's physical device to a Wi-Fi wireless network or 
Ethernet. Provides a solution for the UART data transfer interface. The module comes 
with an RS485 port, a standard RS232 communication port and two RJ45 standard 
network ports. Through this module, the traditional low-end serial device or 
MCU-controlled device can easily access Wi-Fi wireless network or Ethernet. 
Transparent transmission is realized to realize the control and management of the 
Internet of Things. 
As a hotspot, CX-WIFI-2NET module can accommodate 32 wifi clients simultaneously,
