Preface

Introduction

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 and using Wi-Fi

technology, it is 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 the following elements:

• The PICkit

™

On-Board (PKOB nano) supplies full programming and debugging support through Atmel Studio/

MPLAB

X IDE Communication Library. It also provides access to a serial port interface (serial to USB bridge)

and one logic analyzer channel (debug GPIO)

• On the PC, the on-board debugger acts as a mass storage interface device for easy drag-and-drop

programming, Wi-Fi configuration, and full access to the microcontroller application Command Line Interface

(CLI)

• A mikroBUS

™

socket allows for expansion of the board capabilities with the selection from 450+ sensors and

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

™

• A light sensor used to demonstrate published data

• Microchip MCP9808 high-accuracy temperature sensor used to demonstrate published data

• Microchip MCP73871 Li-Ion/LiPo battery charger with power path management
