This is my first ever road test on Element 14. I would like to thank rscasny for giving me this opportunity. I believe that to review a product one has to experience it for the very purpose that it is made for, with this thought I began my RoadTest journey and started exploring the AVR IoT WG development board. I planned to prototype a simple IoT application using the on-board sensors, actuators, and Google Cloud IoT services.
Microchip provides a detailed overview of the board and a getting started video which helps you connect the device to Google Cloud and stream data within 30 seconds. This is where I started exploring the board. You can check the links below.
Out of the box we just get the AVR IoT Development board. A micro-USB cable would have been a good addition to the board. The expansion pins are also not available. In this video, I have given a short overview of the board and soldered the pins to the board. Check this video if you are interested to learn more.
The out-the-box examples which that connects to Google cloud and seamlessly visualize the sensor data on the web site. I was really excited to develop a prototype application on the board. Atmel START helps you get started with developing your prototype. It provides a neat way to develop by providing an infrastructure to configure the projects with different middle-ware and drivers. In this video, I have shown how to add a relay click middle-ware to your project and how to configure it.
Command Line Interface(CLI) demo for debugging your project
The CLI feature of the code is very useful. It helps in connecting to WiFi when the Click-Me.html method doesn't work or the AP mode is not working. You can use the CLI method to reset the device, check the CLI and firmware version, get the public key, connect to wifi, and see the debug messages on the serial terminal. Here is a short demo of all these features. You can see the application demo video on how I use the CLI for checking if the messages are received by the device from the server.
I have tried to demonstrate a prototype application which uses the on-board sensors to send the data to google cloud, visualize the sensor data on the web site. I am running cloud IOT server on a Raspberry Pi which subscribes to the messages and sends commands to the device whether to turn on or turn off the devices connected the relay depending on the sensor data. Check out this video for a short demo. The intent of the project is to evaluate how easy it is to integrate Google's IoT services with AVR IoT WG with a basic application. Challenges and Key learning are summarized below.

Finally, I would like to recommend this board to anyone who wishes to dive into the world of IOT devices powered by the comprehensive cloud services by Google. This board is a complete package to build complex applications. Thank you for reading the review, I would like to leave you with a quote
