Microchip and Google have partnered to provide you with an ideal foundation for building your next cloud-connected design.
Combining powerful microcontrollers, a CryptoAuthentication™ secure element and a fully certified Wi-Fi® network controller these boards offer the most simple and effective way to connect embedded applications to Google's Cloud loT core platform.
Make a direct connection to the Google Global Cache (GGC) edge nodes, pre-provisioned with free sandbox account to see light and temperature data with access to Artificial Intelligence (AI) & Machine Learning (ML) tools and bleeding edge technology.
I could prove that it took me just about 13 seconds instead to connect this AVR®-IoT WG Development Board AC164160-ND vs their promotion: Out of the box & into the Cloud in less than 30 seconds.
For your final prototypes you can choose your favorite AVR® microcontroller to make an easy and secure cloud connection.
At the heart of the loT Development Board is your choice of microcontroller. Choose the AVR® MCU that you are using and most comfortable with.
These powerful and efficient 8-bit MCUs allow you to intelligently bring your data to the Cloud. These scalable MCUs provide you the possibility of expanding upon the loT functionality and add your customized sensors into the application. When you move from prototyping to series production you can keep using your preferred MCU. On this loT Development board there is this fixed ATMEGA4808 AVR® Microcontroller ATMEGA4808-MFRCT-ND.
For rapid prototyping, this loT Development Board is supported by both Studio 7 and MPLAB X IDEs as well as graphical development tools such as START and MCC. These tools simplify connecting existing applications to the cloud or developing new loT designs.
The integrity of any network is determined by its weakest link. As the attack surface of loT devices continues to grow with .... clear acceleration, security can no longer be an afterthought. The loT Development Boards entrust data encryption to the latest in Microchip's CryptoAuthentication™ portfolio, the hardware based ATECC608A Secure Element ATECC608A-MAHDA-SCT-ND. By employing ultra-secure key storage, cryptographic countermeasures and obscuring private keys from both users and software this secure element ensures the highest fidelity of your transmission into the Cloud.
The critical component that propels your design into the Cloud is Microchip's ATWINC1510 (Wi-Fi® Network Controller ATWINC1510-MR210PB-ND) a single-band 2.4GHz Wi-Fi® network controller that was specifically optimized for low power loT applications. Featuring extremely low power consumption, the ability to store various security certificates, and 8Mb of on-board Flash memory, this device offloads all networking tasks from the main CPU while automatically providing a secure socket connection and server authentication to the Google Cloud.
Each board comes pre-associated with a default shared Google Cloud (sandbox) account for immediate successful authentication and data sharing without a custom user account. At any time, the user can disconnect the device from the default sandbox and register to a private account.
The on-board mikroBUS™ connector allows for both the seamless integration of any MikroElektronika ClickBoard™ and the ability to quickly interface with other sensors or actuators that support the popular mikroBUS™ footprint.
With over 500 click boards to choose from this board can rapidly be made into an loT enabled motion detector, heart rate monitor, or anything else you can imagine.
USB Mass Storage interface allows easy drag-and-drop update of the microcontroller Flash memory and configuration of WiFi® credentials. The USB can also be used for diagnostics and to support command line interface.

The AVR-IoT WG Development Board will be introduced in the DK IoT Studio™ as the fastest and simplest way to create, deploy and manage a complete embedded-to-cloud IoT solution at embeddedworld2019 in Nuremberg, Germany our booth number is 633 in hall 4A.
We need to point out that when using the DK IoT Studio, the AVR®-IoT node connects to our default cloud service, which is Amazon AWS in this case and no longer Google Global Cache (GGC).
