Arduino has announced the new UNO R4 board family for prototyping and learning. The new models feature a faster microcontroller, a USB-C connector, improved power, Wi-Fi and Bluetooth LE, and more.

However, the USB port doubles as a power port. To use it as such, you need a USB cable and a 5V power source. In the case of the Arduino Nano, a mini-B USB cable is required.

Arduino said requests from the Arduino community see the USB port upgraded to USB-C and the maximum power supply voltage increased to 24 V with an improved thermal design. The board provides a CAN bus ...
