WHIZFI WHZ4188

WHIZFI WHZ4188

WHZ4188 is a full-featured Wi-Fi 802.11b/g/n WiFi single system module that includes support for high linear output power and IEEE 802.11i security, IEEE 802.11e QoS.

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 an SPI/SDIO 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.

WHZ4188 is an embedded fully integrated IEEE 802.11bgn WiFi SMD module with internal crystal, voltage regulator and ON module U.FL antenna connector. 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.

WHZ4188 is fully integrated 52 pin, small size module. A small form-factor of 18mm x 18mm x 2.2mm reduces board space and low memory footprint WLAN SDK for No OS & RTOS based systems provides a Wireless (WLAN) connectivity to micro-controller based products. The module is available in small to very large quantities.
