Key Features
- IEEE 802.11 b/g/n Wi-Fi connectivity with integrated PCB antenna enables wireless operation from a 2.7 V to 4.8 V RF supply without external antenna design
- Dual-voltage architecture with 2.0 V to 3.8 V I/O supply interfaces directly with 3.3 V MCU GPIO, simplifying host integration in embedded IoT designs
- Integrated TCP/IP stack and AT command interface reduce host MCU firmware complexity, enabling Wi-Fi connectivity with minimal software development effort
Applications
The WGM110A1MV2 is used in industrial sensor gateways, smart home controllers, and building automation nodes where IEEE 802.11 b/g/n Wi-Fi connectivity must be added to an embedded MCU design with minimal RF engineering. Its 2.0 V to 3.8 V I/O supply compatibility and AT command interface allow direct connection to low-power ARM Cortex-M microcontrollers running at 3.3 V. The module is also deployed in medical device monitoring equipment and retail IoT peripherals where a pre-certified Wi-Fi module shortens FCC/CE regulatory approval timelines.

Frequently Asked Questions
What supply voltage ranges does WGM110A1MV2 require for I/O and RF operation?
The WGM110A1MV2 requires a 2.0 V to 3.8 V supply for the I/O interface and a separate 2.7 V to 4.8 V supply for the RF and core circuitry. These dual voltage requirements must both be satisfied for correct Wi-Fi module operation, with the I/O voltage typically set to match the host MCU's 3.3 V GPIO logic level.
Does WGM110A1MV2 include an onboard antenna, and what Wi-Fi standard does it support?
Yes, the WGM110A1MV2 integrates a PCB antenna and supports IEEE 802.11 b/g/n (2.4 GHz band), providing data rates up to 72.2 Mbps at MCS7 in 802.11n mode. The integrated antenna eliminates the need for an external RF connector and antenna component, reducing BOM cost and simplifying enclosure design for compact IoT products.
How does the AT command interface of WGM110A1MV2 speed up embedded Wi-Fi integration?
The AT command interface allows a host MCU to configure Wi-Fi parameters, initiate TCP/UDP connections, and transfer data over a standard UART at rates up to 921600 baud using simple ASCII string commands. This eliminates the need to port a full TCP/IP and Wi-Fi driver stack onto the host processor, reducing firmware development time by weeks compared to bare-metal Wi-Fi driver integration.
Is WGM110A1MV2 suitable for battery-powered IoT devices, and what power modes does it offer?
The WGM110A1MV2 supports low-power sleep modes that reduce current consumption significantly below its active Wi-Fi transmit levels, making it suitable for battery-powered IoT sensors operating on 3.0 V to 3.7 V LiPo cells. Its 2.7 V minimum RF supply voltage allows operation as cell voltage drops during discharge, extending usable battery capacity in remote sensor nodes that wake periodically to transmit data over Wi-Fi.
