WLM400

RF Transceiver Modules And Modems Overview

The Ezurio WLM400 is a WiFi transceiver module supporting the 802.11b/g protocol standard. It operates within the 2.4 GHz frequency band and utilizes an U.FL surface mount interface for antenna connection, which is not included with the unit. The module requires an operating supply voltage ranging from 3.3 V to 5 V. Designed for embedded integration, it serves as a connectivity component for IoT applications requiring wireless data transmission.

RF Transceiver Modules And Modems Procurement Notes

Verify that the specific application circuitry supports the required 3.3 V to 5 V operating voltage range before procurement. Confirm that the system design includes a compatible external antenna connected via the U.FL interface, as the module does not include one. Ensure the PCB layout accommodates the surface mount form factor and RF trace requirements for the 2.4 GHz band to maintain signal integrity.

RF Transceiver Modules And Modems Selection Notes

Select this module when 802.11b/g compatibility is sufficient for the target network environment. Consider the need for an external antenna solution due to the lack of internal antenna inclusion. Evaluate the power supply constraints to ensure stable operation within the specified voltage window. This component is suitable for designs prioritizing compact surface mount integration over high-throughput modern WiFi standards.
