The Arduino team gives a few examples of what you can build using the MKR IoT Carrier Rev2 board : – Environment monitoring stations.

With the arLCD Arduino Library and the Arduino Shield I/O, users can make 3D printer controllers, robot interfaces, home automation controllers, wireless sensors and even kinetic art.

The board is built around an ATtiny3217 and has almost all of the Nano’s features, like a USB port, reset button, built-in LEDs, 5 V regulator, and preloaded bootloader.
