The WHZ5178 is a full-featured Wi-Fi 802.11b/g/n module that includes support for high linear output power and IEEE 802.11i security.

The module is a complete stand-alone device with a small footprint which makes WiFi technology easy to embed into new or existing designs. The module provides SDIO/SPI interface to communicate with a variety of host devices. The pre-tested module eliminates the need to create custom WLAN designs, resulting in greatly reduced development risk, costs and time-to-market.

WHZ5178 is an embedded IEEE 802.11bgn WiFi PCB module created using WHZ4178 to interface directly with the variety of micro-controller. Module supports client and SoftAP mode. Module supports SPI & SDIO interface and has support for no OS, RTOS or Linux based platforms, so you can use the module across your multiple product lines providing you a benefit of lower product cost, inventory cost and learning cost.

WHZ5178 module eliminates the need to create custom WLAN designs, resulting in greatly reduced development risk, costs and time-to-market. A small size 25.4mm x 25.4mm reduces board space and low memory footprint WLAN SDK for no OS, RTOS & embedded Linux provides a Wireless (WLAN) connectivity to micro-controller based products. The module is available in small to large quantities.
