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.

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.
