Microchip AVR-IoT Cellular Mini AVR128DB48 Development Kit Development Board EV70N78A

The AVR-IoT Cellular Mini development board is a hardware platform to evaluate and develop IoT solutions with the Microchip AVR128DB48 AVR® microcontroller, ATECC608B secure element, and the Sequans Monarch 2 GM02S cellular module. Included with the development board is a SIM card from Truphone with 150 MB data ready for activation.

The Sequans Monarch 2 GM02S requires a connection to a LTE-M or NB-IoT capable cellular network. With a connection to a capable cellular network the ATECC608B can be used to authenticate the hardware with the cloud to uniquely identify every board.

Out of the box, the MCU come preloaded with a firmare image that enables you to quickly connect and send data to the Microchip Sandbox in AWS using the on-board temperature and color sensors. Once you are ready to build your own custom design, you can easily get started with development using the Arduino. The AVR-IoT Cellular Mini has full Arduino support through a library build on top of the open-source DxCore.
