AVR-IoT WG Development Board Technical Summary

Preface

The AVR-IoT WG development board is a small and easily expandable demonstration and development

platform for IoT solutions, based on the AVR

microcontroller architecture using Wi-Fi

technology. It was

designed to demonstrate that the design of a typical IoT application can be simplified by partitioning the

problem into three blocks:

• Smart - represented by the ATmega4808 microcontroller

• Secure - represented by the ATECC608A secure element

• Connected - represented by the WINC1510 Wi-Fi controller module

The AVR-IoT WG development board features a USB interface chip Nano Embedded Debugger (nEDBG)

that provides access to a serial port interface (serial to USB bridge), a mass storage interface for easy

‘drag and drop’ programming, configuration and full access to the AVR microcontroller UPDI interface for

programming and debugging directly from Microchip MPLAB

X IDE and the Atmel

Studio 7.0 IDE. The

AVR-IoT WG development board comes preprogrammed and configured for demonstrating connectivity

to the Google Cloud IoT Core.

The AVR-IoT WG development board features two sensors:

• A light sensor

• A high-accuracy temperature sensor - MCP9808

Additionally, a mikroBUS

™

connector is provided to expand the board capabilities with 450+ sensors and

actuators offered by MikroElektronika (www.mikroe.com) via a growing portfolio of Click boards
