Silicon Labs AMWx06 Numbat WICED Wi-Fi Networking Modules

Silicon Labs AMWx06 Numbat WICED Wi-Fi Networking Modules from Silicon Labs combine a microcontroller with a BCM43362 Wi-Fi device. This provides an advanced stand-alone Wi-Fi and networking solution. An integrated module avoids difficult RF layout and allows for quickly embedding Wi-Fi and secure networking functionality into virtually any device. The Silicon Labs WiConnect serial-to-Wi-Fi application is pre-programmed into all modules. It fast-tracks module integration into end-products. The module is suitable for integration into most embedded applications with dimensions of just 20.3x15.2mm and a wide temperature range.

The Wi-Fi device from Broadcom 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. Connections for two external antennas provide applications with maximum radio range and mechanical design flexibility.
