The ATWINC15x0-MR210xB is a low power consumption 802.11 b/g/n IoT (Internet of Things) module,specifically optimized for low power IoT applications. The module integrates Power Amplifier (PA), Low-Noise Amplifier (LNA), Switch, Power Management, and a printed antenna or a micro co-ax (u.FL) connector for an external antenna resulting in a small form factor (21.7 x 14.7 x 2.1 mm) design. It is  interoperable with various vendors’ 802.11 b/g/n access points. This module provides SPI ports to interface with a host controller.
