Important: This document is
applicable for two different products; AVR-IoT WG (AC164160) and AVR-IoT WA
(EV15R70A). Both variants are referred to as AVR-IoT Wx in this document, and both
products have identical hardware. AVR-IoT WG is preconfigured to send data through
Google Cloud IoT Core, and AVR-IoT WA is preconfigured to send data through Amazon
Web Services (AWS). Both products can be reconfigured to send data to different
cloud providers.
Introduction
The AVR-IoT Wx 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 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 ATWINC1510 Wi-Fi controller module
- The on-board debugger (PKOB nano) supplies full programming and debugging support through Atmel Studio/MPLAB X IDE. It also provides access to a serial port interface (serial to USB bridge) and two logic analyzer channels (debug GPIO).
- The on-board debugger enumerates on the PC 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 the ability to expand 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
