Board Overview
The AVR-IoT Wx development board is a hardware platform to evaluate and develop IoT solutions with the Microchip
ATmega4808 AVR microcontroller, ATECC608A secure element, and WINC1510 Wi-Fi controller module.
The preprogrammed demo application publishes data from the on-board light and temperature sensor read by the
ATmega4808 every second to the cloud. 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 WINC1510 needs a connection to a Wi-Fi
network with an internet connection. The ATECC608A is used to authenticate the hardware with the cloud to uniquely
identify every board. The demo application source code can be modified to publish data to a personal cloud account
to get started with a custom cloud application.
The figure below shows the main features and pinout of the board.
