Introduction

The Wi-Fi® link controller module WILCS02 is a low-power 2.4 GHz IEEE® 802.11b/g/n compliant, fully Radio Frequency (RF) certified wireless module designed for Internet of Things (IoT) applications. This module is interfaced to a host microcontroller though Secure Digital Input Output (SDIO) interface.

The module operates at a single supply voltage VDD (3.3V typical), certain Input Output (IOs) pins support a voltage range of 1.8-3.6V by supplying the VDDIO pin separately.

The WILCS02 Module is available with an on-board Printed Circuit Board (PCB) antenna or U.FL connector for an external antenna.
