Zentri AMW037 Wi-Fi® Module

Wi-Fi networking module for low cost IoT edge devices

The AMW037 is a Wi-Fi networking module complete with an onboard PCB antenna and full regulatory certification designed for low cost IoT edge devices.

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 ZentriOS-Lite embedded operating system, designed to enable fast product development. With dimensions of just 12 mm x 11 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 AMW037 microcontroller core operates at a frequency up to 80 MHz and offers extensive I/O and peripheral interfaces.

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.
