MICROCHIP ATWINC1500-MR210PA

The ATWINC1500-MR210PA is a low-power consumption 802.11 b/g/n IoT (Internet of Things) module which is specifically optimized for low power IoT applications. The highly integrated module features small form factor (21.5mm x 14.5mm x3.4mm) while fully integrating Power Amplifier, LNA, Switch, Power Management, and PCB antenna. With seamless roaming capabilities and advanced security, it could be interoperable with various vendors’ 802.11b/g/n Access Points in wireless LAN. The module provides SPI and UART to interface to host controller.
