WGM110 Wizard Gecko Wi-Fi Module Data Sheet The Wizard Gecko WGM110 is an all-inclusive Wi-Fi Module targeted for applications KEY POINTS where good RF performance, low-power consumption, and easy application develop- ment, together with fast time to market, are key requirements. WGM110 has excellent RF performance and can provide long range with robust wireless connectivity. Module variants WGM110A (chip antenna) The WGM110 Module integrates all of the necessary elements required for an IoT Wi-Fi WGM110E (u.FL connector) application, including an 802.11b/g/n radio, integrated chip antenna (WGM110A) or an 802.11b/g/n compliant u.FL connector for an external antenna (WGM110E), certifications, a microcontroller, TX power: +16 dBm Wi-Fi and IP stacks, an HTTP server, and multiple protocols, such as TCP and UDP. RX sensitivity: -98 dBm WGM110 can act as a Wi-Fi client or be used as a Wi-Fi access point, making the provi- Range: up to 450 m sioning of the device as easy as surfing on the web. WGM110 can host BGScript end CPU core: 32-bit ARM Cortex-M3 user applications, which means applications can be designed without relying on an ex- Flash memory: 1 MB ternal microcontroller. Alternatively, the Wi-Fi Module can run in Network Co-Processor RAM: 128 kB (NCP) mode, leaving the complexity of TCP/IP networking to the Module so that the cus- tomers own host controller can be fully dedicated to processing the customer applica- Modular certification tion tasks. The WGM110 Module also has highly flexible hardware interfaces which al- FCC lows connection to different peripherals and sensors. IC Japan In addition to the Wi-Fi Module itself, Silicon Labs offers support to guide and help de- Korea velopers in using WGM110 to build IoT applications, enabling a quick time to market.
