KEY POINTS N ew 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. D es ig ns WGM110 Wizard Gecko Wi-Fi ® Module Data Sheet 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 (WGM110A) or an u.FL connector for an external antenna (WGM110E), certifications, a microcontroller, Wi-Fi and IP stacks, an HTTP server, and multiple protocols, such as TCP and UDP. m en de d fo r 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 WGM110 Module also has highly flexible hardware interfaces which allows connection to different peripherals and sensors. • WGM110E (u.FL connector) • 802.11b/g/n compliant • TX power: +16 dBm • RX sensitivity: -98 dBm • Range: up to 450 m • CPU core: 32-bit ARM® Cortex-M3 • Flash memory: 1 MB • RAM: 128 kB • Modular certification • FCC • IC • Japan • Korea • CE compliant • End-to-end security • Can host applications • Small size: 21.0 x 14.4 x 2.0 mm N ot R ec om In addition to the Wi-Fi Module itself, Silicon Labs offers support to guide and help developers in using WGM110 to build IoT applications, enabling a quick time to market. • Module variants • WGM110A (chip antenna) silabs.com | Building a more connected world.

Pinout This section describes the pinout of the WGM110 Module. fo r N ew D es ig ns Pads in the middle of the Module are intended for ground connections and for RF test and production programming, while pads on the Module edges consist of general purpose input/output, power supply voltage input, ground, and reset signal connections. m en de d Figure 2.1. WGM110 Pinout (Top View) 2.1 Power, Ground and Reset Pads The table below lists the power, ground, and reset pads of the WGM110 Module. Table 2.1. WGM110 Power, Ground, and Reset Pads Function Description 38, 51 VDDCPU Processor core and peripheral interface power supply. 39 VDDPA om Pad number Ground. All ground pads are connected together internally. Connect ground pads directly to a solid ground plane with maximum number of vias in close proximity to pads especially at the antenna end. N ot R ec 1, 16, 25, 40, GND 42, 44, 46, 48 RF power amplifier and Wi-Fi core power supply 24 37, 49 VBUS These ground pads also act as thermal paths which should be used to conduct heat from the module to the PCB. Do not use thermal reliefs on ground pads. USB VBUS detect input is used to detect the presence of an external USB port bus voltage. When USB is not used connect VBUS to VDDCPU. RESETn Reset signal input. To reset the Module pull this line low. The reset signals resets both the MCU and the Wi-Fi radio. Connected to an internal pull-up, can be left floating if not needed. silabs.com | Building a more connected world.

The default state of the GPIO pins after reset is "disabled". fo r For more information on how to configure the GPIO pins and modes, see WGM110 API Reference Manual. 2.2.5 Interrupt Pins Example: m en de d All GPIO pins may be used as interrupts. WGM110 supports up to 14 asynchronous external pin interrupts with the following limitations: • All pins with the same number are grouped together and multiplexed to trigger one interrupt. • Pin 0 from any port cannot be used as an interrupt, because it is reserved for the Module’s internal operation. • Pin 8 of Port A - F is not available for external use. • If PB11 is used as an interrupt pin, then the use of Pin 11 of any other available port as an interrupt is not allowed (PE11 and PF11 cannot be used as an interrupt). 2.3 Debug and RF Test Pads N ot R ec om The table below indicates the pads available for debug and RF test connections. silabs.com | Building a more connected world.

Interfaces This section describes the features and functionalities of the available host, peripheral, debug, and RF test interfaces. 3.1 Host Interfaces es ig ns There are three available host interfaces one of which can be used to connect an external host, typically an MCU, to the WGM110 WiFi Module and use it as a Wi-Fi modem. 3.1.1 UART UART is one of the available host interfaces on the WGM110 Module, and it is also the default host interface for the WGM110 Modules delivered from the factory. D When using WGM110 UART in transparent mode, we highly recommend to use flow control to avoid the possibility of losing data. Futhermore, we recommend to use DMA on the receiving host, because the SW emulated flow control used in the WGM110 is not as fast as HW flow control, and therefore when CTS is raised, module will most likely still send at least one extra byte. Also using lower baud rates (
