Introduction

The WGM110 Wi-Fi Expansion Kit is an excellent way to explore and evaluate the WGM110 Wi-Fi Module with an EFM32 MCU for your embedded application. The kit contains a Wireless Expansion Board (BRD8016A) and a WGM110 Wi-Fi Module Radio Board (BRD4320A). The WGM110 Wi-Fi Module is an easy to use and easy to interface Wi-Fi Network Co-Processor (NCP). Most of the associated complexity of Wi-Fi and the protocol stack is offloaded to the module and allows for easy Wi-Fi integration into any embedded system. The kit easily integrates and brings Wi-Fi connectivity to a compatible Silicon Labs MCU Starter Kit through the expansion header. The Wireless Expansion Board has also been designed after the Raspberry Pi Hardware Attached on Top (HAT) board specification, allowing the WGM110 Wi-Fi Expansion Kit to connect to a Raspberry Pi. The Wizard Gecko WGM110 is an all-inclusive Wi-Fi Module targeted for applications where good RF performance, low power consumption, and easy application development, together with fast time to market, are key requirements. WGM110 has excellent RF performance and can provide long range with robust wireless connectivity. The WGM110 Module integrates all of the necessary elements required for an IoT Wi-Fi application, including an 802.11b/g/n radio, integrated chip antenna, certifications, a microcontroller, Wi-Fi and IP stacks, an HTTP server, and multiple protocols, such as TCP and UDP. WGM110 can act as a Wi-Fi client or be used as a Wi-Fi access point, making the provisioning of the device as easy as surfing on the web. WGM110 can host BGScript end user applications, which means applications can be designed without relying on an external microcontroller. Alternatively, the Wi-Fi Module can run in Network Co-Processor (NCP) mode, leaving the complexity of TCP/IP networking to the Module so that the customer’s own host controller can be fully dedicated to processing the customer application tasks. The Wi-Fi expansion kit provides the ability to pair up the WGM110 Wi-Fi Module with an EFM32 host running the user application, using the module as a network co-processor. The kit provides the Wireless EXP Board and a WGM110 Wi-Fi Module Radio Board, and should be used together with a Silicon Labs MCU Starter Kit, such as the EFM32 Pearl Gecko PG12 STK. NCP mode of operation is the primary focus of this kit. For standalone application development, the Wizard Gecko Wi-Fi Module Wireless Starter Kit (SLWSTK6120A) is recommended instead.
