Wi-Fi Xpress AMW037 Wi-Fi® Module

Wi-Fi networking module for low cost IoT edge devices

The Wireless Xpress AMW037 is a low cost Wi-Fi networking module that comes with an onboard PCB antenna, full regulatory certification and supports the Xpress Command API for fast and simple Internet connectivity in your products.

The AMW037 module is an advanced stand-alone Wi-Fi and networking solution.It is an integrated module designed to avoid difficult RF layout and to enable designers to rapidly embed Wi-Fi and secure networking functionality into virtually any device. Each AMW037 is pre-installed with the Gecko OS IoT operating system, designed to enable fast product development. With dimensions of just 16.5 x 24.8 x 2.6 mm and a wide temperature range, the module is suitable for integration into most embedded applications.

The Wi-Fi device includes an integrated RF transmit power amplifier and provides superior Wi-Fi performance and full compatibility with all 2.4 GHz 802.11b/g/n Wi-Fi networks.

The module is powered by a single 3.3 V power supply and various powersave modes offer ultra-low power operation. Wake from low power sleep mode is possible using IO pins or the internal real-time clock; wake from ultra-low power standby mode is achieved using the dedicated wake pin.

The module has FCC & IC modular approval for use in the United States and Canada, CE approval for use in Europe and related approvals for use in other countries.
