The WG219 WiFi Module is a small form-factor, single-stream, 802.11b/g/n WiFi module with an onboard low power application processor. It is a low-cost serial WiFi module, supports UART-WiFi - Ethernet data transmission.

The WG219 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 WG219 Wi-Fi Module also enables rapid application development of ultra low power devices with the complete application SW on-chip.

This combination makes the WG219 WiFi Module an ideal solution for low power automation and sensor solutions because of its high efficiency and low power consumption.

The WG219 WiFi 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.
