This USB WiFi module is a complete and self-contained WiFi network solution that can operate independently or as a slave on other host MCUs. It can be booted directly from an external flash when it is powered by an application and is the only application processor in the device. The built-in cache helps improve system performance and reduce memory requirements. When it comes to the task of the WiFi adapter, it can be added to any microcontroller-based design. The connection is simple and easy, just through the SPI / SDIO interface or I2C / UART port. Just fine. With the addition of powerful on-chip processing and storage capabilities the module is able to integrate sensors and other application-specific devices through the GPIO port, minimising system resources during minimal up-front development and operation.

This USB WiFi module is highly integrated on-chip, including the antenna switch balun, power management converter, so only a small amount of external circuitry is required, and the entire solution, including the front-end module, minimises PCB space during design.
