Preface
Introduction
The AVR-IoT WA 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 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 two logic analyzer channels (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
