User Manual
General Description
The WG231 Wi-Fi Module is a small form-factor, single stream, 802.11b/g/n WiFi module with
on-board low power application processor. It is a low cost serial WiFi module, support UART-WiFi Ethernet data transmission. The WG231 has been optimized for client applications in the home,
enterprise, smart grid, home automation and control that have lower data rates and transmit or receive
data on an infrequent basis. The WG231 Wi-Fi Module also enables rapid application development of
ultra low power devices with the complete application SW on-chip . This combination makes the
WG231 Wi-Fi Module an ideal solution for low power automation and sensor solutions because of its
high efficiency and low power consumption.
The WG231 Wi-Fi Module can be used to design applications using 802.11b/g/n communication
protocols. All features are enhanced by a built-in antenna, external antenna connector and an
interface port to the carrier board. This interface port includes power supply pins, GPIO ports and
UART ports.
