PRE-ANNOUNCING the AMW037 'Spectre', 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 from Zentri 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 AMW007 is pre-installed with the ZentriOS-Lite embedded operating system, designed to enable fast product development. With dimensions of just 12mm x 11mm 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 2.4GHz 802.11b/g/n Wi-Fi networks.

The AMW037 microcontroller core operates at a frequency up to 80MHz and offers extensive I/O and peripheral interfaces.

The module is powered by a single 3.3V power supply and various power-save 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.

Symmetry Electronics is an authorized Silicon Labs distributor.
