WFM200S Series 2 Wi-Fi Transceiver Modules

WFM200S modules form the perfect certified Wi-Fi transceiver secure, low-power IoT Wi-Fi applications. The Wi-Fi transceiver contains a 2.4 GHz 802.11b/g/n radio (MAC and PHY layer), optimized for low power and optimal RF performance in crowded RF environments, supporting Linux-based and RTOS-based hosts to deliver a complete Wi-Fi solution. High-speed SPI and SDIO host interfaces provide flexibility and throughput. An optional secure link interface between the host and the transceiver enhances security. Modules are fully certified with the transceiver, antenna, crystal and passives all built into a tiny package with support for up to 105 °C operation.

Ideally suited for home automation products like security cameras, motion detectors, smart locks, video doorbells, thermostats and smoke detectors. In the industrial and consumer space, ideal applications are point-of-sale-terminals, portable printers, wireless tools and wireless sensors.
