Microchip Technology AVR-IoT Cellular Mini Development Board (EV70N78A)

Microchip Technology AVR-IoT Cellular Mini Development Board (EV70N78A) is a complete platform that can be used to evaluate and develop IoT solutions. It features the AVR128DB48 AVR® microcontroller, ATECC608B secure element, and the Sequans Monarch 2 GM02S cellular module. Sensors and actuators can be added using the onboard Adafruit Feather compatible edge connector or Qwiic® I²C connector. The Amazon Web Services and Arduino-compatible Development Board also includes a Truphone SIM card.
