Board Overview

The SAM-IoT Wx v2 development board is a hardware platform used to evaluate and develop IoT solutions with
the Microchip ATSAMD21G18 Arm Cortex-M0+ based Flash microcontroller, ATECC608B secure element, and the
ATWINC1510 Wi-Fi controller module.
The pre-programmed demonstration application publishes data from the on-board light and temperature sensors read
by the ATSAMD21G18A MCU to the cloud (every second). Any data received from the cloud over the subscribed
topic is sent to the virtual serial port and can be displayed in a serial terminal application. The ATWINC1510 needs a
connection to the Wi-Fi network with an internet connection. The ATECC608B is used to authenticate 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 to begin with a custom cloud application.
The following figure shows the key features and pinout of the SAM-IoT Wx v2 development board.
