1. Introduction
FLC-CBM202 is a highly integrated module that combines WiFi and BT in a small single package.
The module supports SDIO and CSPI host interfaces for WiFi and UART for BT that make it simple
to design into fully certified embedded WiFi and BT solutions.
The module is an appropriate product for designers who want to add wireless capability to their
products.
