Arduino Nano Board R3 with CH340 chip without USB Cable
Based on the Atmega328 SMD Package Microcontroller, the Arduino NANO Version 3 is the open source smallest Embedded Development board released by Arduino. It's a Surface Mount Breadboard Compatible board with a Mini USB Port. Because this board lacks a DC power jack, power is provided via a Mini USB cable. There is no need for the power choose jumper because it automatically detects and switches to the greater potential source of power.
