USB-C-Arduino-Slim

Download here
An Arduino board with USB C port for data transfer and power.
It bit lengthier than Nano. Because it has 2 voltage regulators(5V and 3.3V)

I'm not sure this is working or not.

I was not aware of Atmega328p-QFN prices🥲,So I can't test it.
Also seems like 5V regulator is of no use in this, I could run the Atmega328 on 3.3V.
