Robust SoCs and Modules for Linux® Applications


Link controllers are simple solutions for adding Wi-Fi or Wi-Fi and Bluetooth® connectivity. Unlike other Wi-Fi devices like microcontrollers (MCUs) or network controllers, link controllers do not have an on-board network stack. For this reason, they are best used as a companion device to an advanced processor. In many cases, they’re used with microprocessors (MPUs) can also accompany high-performance MCUs.

Because the application and network functions are handled by another device, link controllers are often faster and more cost effective than more complex Wi-Fi products. These qualities make them excellent candidates for industrial applications running on the Linux Operating System (OS).

In addition to supporting both RTOS and Linux OS, our Wi-Fi link controller modules and SoCs provide robust connectivity, seamless integration and enhanced security.

In this demo, you’ll create a heart rate monitor using Linux/Python-based code, Azure IoT hub and web apps.

Getting Started with Wi-Fi for Linux


Add Wi-Fi functionality to your embedded Linux application using our ATWILC1000-SD or ATWILC3000-SD Evaluation Kit. These kits are based on our WILC family of Wi-Fi link controller modules and are plug-and-play compatible with the SAMA5D27 microprocessor (MPU) evaluation platform.

Along with plug-and-play compatibility, these boards come with easy-to-follow instructions plus supporting tools and documentation to help you get the demo running.
