WG222 is a highly integrated WiFi/Bluetooth combo module which features an application processor, a low power 1x1 802.11n dual-band Wi-Fi subsystem, a Bluetooth subsystem, and a Power Management Unit.

The application processor subsystem contains an ARM Cortex-M4F MCU. It also includes many peripherals, including UART, I2C, SPI, I2S, PWM, IrDA, and auxiliary ADC. It also includes embedded SRAM/ROM. The Wi-Fi subsystem contains the 802.11a/b/g/n radio, baseband, and MAC that are designed to meet both the low power and high throughput application. It also contains a 32-bit RISC CPU that could fully offload the application processor. The Bluetooth subsystem contains the Bluetooth radio, baseband, link controller. It also uses the same 32-bit RISC CPU for the Bluetooth protocols. The module requiring only an external 3.3V power supply. Below is the module top view.
