The WHZ9189 is a small form factor, single stream, 801.11 b/g/n WiFi Module with embedded low power application processor. The module 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 module integrates all WiFi functionality into a low-profile, 19mm x 22.25mm SMT module package that can be easily mounted on a low-cost main PCB with application specific circuits. The module includes an integrated antenna, variant for connecting external antenna using U.Fl antenna connector.

The module offers a flexible Interface includes SPI, I2C, I2S, PWM, PCM, UART, and ADC Ports. The module combines an ARM-Cortex M3 MCU, WLAN MAC, a 1T1R capable WLAN baseband, and RF in the board. It also provides configurable GPIOs which are configured as digital peripherals for different applications and control usage.

The pre-certified module eliminates the need to create custom IoT solution designs, resulting in greatly reduced development risk, costs and time-to-market.
