Overview
The SAM-IoT Wx v2 Development Board is a small and easy-to-expand hardware platform used to evaluate and develop IoT solutions. It features our ATSAMD21G18 Arm® Cortex®-M0+ based Flash microcontroller (MCU), ATECC608B secure element and the ATWINC1510 Wi-Fi® controller module, and it can be reconfigured to send data to a variety of cloud service providers.
The ATSAMD21G18A MCU reads the data from the on-board light and temperature sensors, and the pre-programmed demonstration application then publishes this data to the cloud every second. Any data the cloud receives from the sensors is sent to the virtual serial port and can be displayed in a serial terminal application. The ATWINC1510 Wi-Fi controller module needs a connection to the Internet-enabled Wi-Fi network. The ATECC608B secure element authenticates the hardware with the cloud to uniquely identify every board. The demonstration application source code can be modified to publish data to a personal cloud account, if you would like to create a custom cloud application.
